Description

Electric carrying test vehicle and control method thereof
Technical Field
The invention relates to a carrying tool, in particular to an electric carrying test vehicle and a control method thereof.
Background
With the development of commercialization, the demand of transportation means in the field of logistics is increasing, and transportation means and handling means become important means for loading and transporting goods. For example, in a warehouse, the classified placement and transportation transfer of goods are completed by using a carrying tool, and the carrying efficiency is low, the time consumption is long and the cost is high due to the adoption of manual labor. Moreover, the existing carrying tool is only suitable for flat ground, has low adaptability to gradient and camber, is slow in reaction and cannot accurately work. That is, the conventional carrying tool is greatly influenced by environmental factors, and for example, in a plot terrain or other terrains having a slope, the conventional carrying tool has poor passing performance and stability.
In addition, in the field of elevator testing, there are no specialized vehicles for elevator testing. The elevator is a common transportation tool in daily life, and the safety of the elevator is very important. In order to ensure the safe operation of the elevator, the safety of the elevator needs to be detected not only when the elevator is checked and accepted, but also periodically during the use process of the elevator. During the inspection of elevators, the balance factor, the load bearing factor, the braking factor, etc. of the elevator are usually tested and measured. At present, in the test of an elevator, the above coefficients of the elevator are usually tested and evaluated through test weights with different masses, 1600kg and above test weights are needed in the test process, and the test weights are mainly carried in a manual carrying mode at present. It is worth mentioning that the traditional test weights are generally 20kg, 25kg and 35kg in specification, so the number of test weights to be carried is large, according to human engineering, the capacity of a normal person to take heavy objects is generally 10kg-20kg, and because the traditional test weights exceed the range, muscle injury or lumbar vertebra diseases of a human body are easily caused when the traditional test weights are carried manually. Moreover, because the number of test weights to be tested is large, the efficiency is low through a manual carrying mode, the time consumption is long, and the cost is high. In addition, in the test of the load-bearing coefficient and the braking coefficient of the elevator, 50% -125% of the load-bearing number of the elevator needs to be tested in a plurality of times, so that a plurality of test tests need to be carried out, and in the process of the plurality of tests, the weight of the test weight needs to be controlled and adjusted, namely, the test weight needs to be moved in and out and loaded or unloaded, so that if the test weight is manually moved, the fatigue of manpower to a large extent can be caused. It is also worth mentioning that the specifications of conventional test weights have limitations, and the weights can only be adjusted by integer multiples of the weight of conventional test weights, but cannot be flexibly adjusted according to various weights of elevator tests. In addition, it is worth mentioning still that, though can also pass through the transport test weight of trailer help at present, because current trailer volume is great and can't directly pass in and out the elevator, consequently current trailer can only carry the test weight to the elevator gate usually, relies on the manpower to carry the test weight again. In addition, due to the volume and weight limitations of the existing trailer and the weight limitations of the test weight, the existing trailer and the test weight can only be transported by a truck with larger volume, so that the transportation and elevator test costs are greatly increased.

Referring to fig. 1 to 11 of the drawings, the electric carrier test vehicle 100 according to a preferred embodiment of the present invention is illustrated. As shown in fig. 1 to 7, wherein the electric carrier test vehicle 100 is adapted to carry elevator test weights and includes a vehicle frame 10, a load-bearing wheel assembly 20 and a driving mechanism 30, wherein the vehicle frame 10 includes a bottom frame 11 and a support frame 12 connected to the bottom frame 11, wherein the support frame 12 includes a guide frame 121 vertically disposed on the bottom frame 11 and a carrier frame 122 slidably disposed on the guide frame 121, wherein the carrier frame 122 is perpendicular to the guide frame 121, so that the carrier frame 122 can be slid on the guide frame 121, thereby allowing the center of gravity of the electric carrier test vehicle 100 to be adjusted; wherein the load bearing wheel assembly 20 is disposed at the second end 112 of the chassis 11; wherein the driving mechanism 30 is operatively disposed at the first end 111 of the chassis 11 and is configured to drive the load-bearing wheel assembly 20 to move, wherein when the driving mechanism 30 is driven, the load-bearing wheel assembly 20 is driven by the driving mechanism 30 to move, so that the electric carrier test vehicle 100 is driven to move.
It can be understood that, the driving mechanism 30 is supported at the first end 111 of the chassis 11, so that when the supporting frame 12 is loaded with the elevator test weight, the driving mechanism 30 and the elevator test weight carried by the supporting frame 12 can balance the center of gravity of the electric vehicle 100, which is beneficial to the smoothness of carrying the electric vehicle 100.
It should be noted that, the guide frame 121 of the support frame 12 may be fixedly connected to the bottom frame 11 or slidably disposed on the bottom frame 11, which is not limited in the present invention. Preferably, in the preferred embodiment of the present invention, the guide frame 121 is slidably disposed on the chassis 11, so that the center of gravity of the electric carrying test vehicle 100 can be adjusted, which is beneficial to the smoothness of carrying the electric carrying test vehicle 100.
It is understood that, in the case where the guide frame 121 of the support frame 12 is vertically disposed on the base frame 11 and the carrier frame 122 is vertically disposed on the guide frame 121, the carrier frame 122 is slidably disposed on the guide frame 121 in parallel with the base frame 11, so it is understood that the guide frame 121 can be slid in the extending direction of the base frame 11, i.e., the lateral direction of the electric carrier test vehicle 100, with respect to the base frame 11, and the carrier frame 122 can be slid in the direction perpendicular to the base frame 11, i.e., the longitudinal direction of the electric carrier test vehicle 100, with respect to the guide frame 121, the overall center of gravity of the electric carrier test vehicle 100 can be adjusted. Therefore, when the elevator test weight is carried by the carrier 122, the gravity center of the whole electric vehicle 100 can be adjusted through the sliding adjustment of the guide frame 121 and the carrier 122, so that the electric vehicle 100 can smoothly carry the elevator test weight, and the whole gravity center of the electric vehicle 100 and the elevator test weight carried by the electric vehicle 100 can be conveniently consistent with the gravity center of the elevator, thereby ensuring the accuracy of the test in the elevator test process.
In other words, the slidable arrangement of the guide frame 121 and the carrier frame 122 enables the distance of the guide frame 121 relative to the driving mechanism 30 and the distance of the carrier frame 122 relative to the base frame 11 to be flexibly adjusted, so that the overall gravity center of the electric vehicle 100 can be adjusted, thereby enabling the gravity center of the electric vehicle 100 to be correspondingly adjusted relative to the weight of the elevator test weight when the electric vehicle 100 carries the elevator test weights with different weights, thereby facilitating the application of the electric vehicle 100 in elevator testing.
Further, the guiding frame 121 has two guiding rods 1211 vertically disposed on the bottom frame 11, wherein each guiding rod 1211 is disposed with a guiding rail 1212, wherein the carriage 122 includes at least one pulley block 1223, wherein the pulley block 1223 is slidably disposed on the corresponding guiding rail 1212, thereby forming a state that the carriage 122 is slidably disposed on the guiding frame 121.

It is understood that two of the guide rails 1212 are oppositely disposed inside the corresponding guide rods 1211, wherein when the pulley blocks 1223 of the carriage 122 are slid at the guide rails 1212, the distance of the carriage 122 relative to the base frame 11 is adjusted, so that the center of gravity of the electric vehicle 100 for carrying the elevator test weight can be correspondingly adjusted through the adjustment of the distance of the carriage 122 relative to the base frame 11 and the adjustment of the distance of the guide frame 121 relative to the driving mechanism 30.
In particular, the guide frame 121 further includes a limiting rod 1213, wherein two ends of the limiting rod 1213 are respectively connected to the corresponding guide rods 1211 to limit the position of the carrier 122 within the sliding path of the carrier 122 in the guide frame 121, that is, the limiting rod 1213 is configured to block the position of the carrier 122 to prevent the carrier 122 from being pushed excessively. Alternatively, the limiting rod 1213 may be connected to the two guide rods 1211 by welding, or may be connected to the two guide rods 1211 by screwing, which is not limited by the present invention.
Further, the base frame 11 includes two bearing rods 113, wherein the two guide rods 1211 of the guide frame 121 and the corresponding bearing rods 113 are connected by a sliding slot and a sliding rod to form a state in which the guide frame 121 is slidably disposed on the base frame 11.
Specifically, when the guide rod 1211 is slid on the bearing rod 113, the distance of the guide frame 121 relative to the driving mechanism 30 is adjusted, that is, the guide frame 121 can be moved in the transverse direction of the electric carrier test vehicle 100, so that the position of the carrier frame 122 relative to the electric carrier test vehicle 100 can be adjusted by the movement of the carrier frame 122 in the longitudinal direction of the electric carrier test vehicle 100 and the movement of the guide frame 121 in the transverse direction of the electric carrier test vehicle 100, and therefore, when the elevator test weight is carried by the carrier frame 122, the center of gravity of the whole electric carrier test vehicle 100 can be adjusted by adjusting the positions of the guide frame 121 and the carrier frame 122.
It is understood that the guide frame 121 and the base frame 11 may be further provided with a stopping device, wherein when the carrier frame 122 and the guide frame 121 are slid to a desired distance, the stopping device can lock the position of the carrier frame 122 and/or the guide frame 121, so that the position and distance of the carrier frame 122 relative to the base frame 11 and the guide frame 121 relative to the driving mechanism 30 are fixed, that is, the position of the carrier frame 122 relative to the whole vehicle of the electric carrying test vehicle 100 is fixed, to facilitate the adjustment of the gravity center of the whole vehicle of the electric carrying test vehicle 100.
It should be noted that the base frame 11 further includes a connecting rod 114, and two ends of the connecting rod 114 are respectively connected to the corresponding bearing rods 113 so as to be able to limit the position of the guide frame 121 in the sliding path of the guide frame 121 on the base frame 11.
Specifically, one end of each of the two bearing rods 113 of the chassis 11, which is away from the driving mechanism 30, is provided with a mounting portion 1131, wherein the bearing wheel assembly 20 includes two bearing wheels 21, and the two bearing wheels 21 are respectively provided on the mounting portions 1131, wherein when the driving mechanism 30 is activated, the bearing wheels 21 are linked to rotate.
It can be understood that, the mounting portion 1131 is recessed so as to be able to mount the bearing wheel 21 on the mounting portion 1131 without increasing the width of the whole electric carrying test vehicle 100, so as to be able to facilitate the miniaturization of the electric carrying test vehicle 100.
In particular, the tires of the bearing wheels 21 are made of Polyurethane (PU) material, so that the tires can prevent the tile and marble floor from being damaged while being anti-skid.
It is worth mentioning that, in the preferred embodiment of the present invention, the overall vehicle height of the electric carrying test vehicle is set to be less than or equal to 1200mm, the distance by which the carriage 122 is slid relative to the base frame 11 on the guide frame 121 ranges from 80mm to 800mm, wherein the entire length of the electric carrying test vehicle 100 is set to be 1250mm or less, wherein the length of the carriage 122 is set to 750mm, wherein the guide frame 121 is slid with respect to the driving mechanism 30 by a distance ranging from 0mm to 750mm, that is, the carrier frame 122 of the electric carrier test vehicle is slidably disposed within the height range of the electric carrier test vehicle 100, and the guide frame 121 is slidably disposed within the length of the electric carrier test vehicle 100, thereby facilitating the electric carrying test vehicle 100 to be miniaturized while allowing for the center of gravity thereof to be adjusted. In other words, the guide frame 121 and the carrier frame 122 are slidably disposed in the lateral space and the longitudinal space of the electric vehicle 100, so that the electric vehicle 100 can be miniaturized and the center of gravity of the electric vehicle 100 can be adjusted, thereby the electric vehicle 100 has good passing performance and stability.
In particular, in the preferred embodiment of the present invention, the length of the whole electric vehicle 100 is set to be 1250mm or less, the width of the whole vehicle is set to be 760mm or less, the height of the whole vehicle is set to be 1200mm or less, and the standard clear size range of the existing elevator (elevator with standard load of 630 kg-1600 kg) is 800 mm-1100 mm, the standard height size is 2100mm, and the standard length size is 1400-1500 mm, so that the electric vehicle 100 can enter and exit the existing elevator, the electric vehicle 100 has good passing performance, so that when the electric vehicle 100 is used for carrying the elevator test weight, the electric vehicle 100 can enter the elevator together with the elevator test weight, and the weight range of the electric vehicle 100 is 400kg-500kg, the electric vehicle 100 can also be used as the elevator test weight. Therefore, when the electric vehicle 100 is used for elevator testing, fewer elevator testing weights can be used than in conventional testing, that is, since the electric vehicle 100 can enter and exit an elevator and can be used as a part of the elevator testing weights, the electric vehicle 100 can meet the testing requirement of elevator load bearing by only carrying a smaller number of the elevator testing weights.
In addition, the rated load of the electric vehicle test vehicle 100 is 1500kg, and the elevator test weights with different weights can be loaded, so that when the weight test of 40%, 50% and 125% of the elevator load is performed, the electric vehicle test vehicle 100 and the elevator test weights can be used as an integrated weight module for testing, so that when the electric vehicle test vehicle 100 is applied to the elevator test, the specification of the elevator test weights is not limited, and the elevator test weights are flexible and convenient.
In addition, it is worth mentioning that the climbing gradient range of the electric carrying test vehicle 100 when the electric carrying test vehicle is fully loaded or unloaded is 15 ° to 25 °, so that the electric carrying test vehicle 100 can have good climbing performance when carrying the elevator test weight, so as to facilitate the electric carrying test vehicle 100 to walk on a slope section, and therefore the electric carrying test vehicle 100 is suitable for passing through a terrain with a slope and has good passing performance.
In addition, the turning radius of the electric carrying test vehicle 100 is set to be 1250mm or more, so that the electric carrying test vehicle 100 can pass through the passage of the elevator conveniently and facilitate the right-angle turning.
It can be understood that the electric carrying test vehicle 100 has good climbing performance and turning performance so as to pass through various terrains and have good passing performance.
It can be understood that, because the electric carrying test vehicle 100 can get in and out of the elevator, the elevator test weight can be carried by the electric carrying test vehicle 100 into and out of the elevator without manual carrying, thereby relieving the manpower, and moreover, the electric carrying test vehicle 100 can mechanically load and unload the elevator test weight, thereby avoiding fatigue damage caused by manual carrying for many times and saving labor cost.
It is also understood that since the electric carrying test vehicle 100 is provided in a miniaturized configuration, the transportation of the electric carrying test vehicle 100 can be facilitated.
It is worth mentioning still that, wherein electric carrying test car 100 can pass in and out the elevator and its focus can be adjusted, consequently electric carrying test car 100 carries after the elevator test weight gets into the elevator, can adjust electric carrying test car 100's whole car focus is unanimous with the focus of elevator to ensure the accuracy of elevator test. Because the size of the electric carrying test vehicle 100 is slightly smaller than the size of the elevator, the electric carrying test vehicle 100 can be guaranteed to have the maximum stability of the electric carrying test vehicle 100 while getting in and out of the elevator, in other words, the electric carrying test vehicle 100 is provided with the maximum volume suitable for getting in and out of the elevator, so that the electric carrying test vehicle 100 can have good stability performance and can facilitate the adjustment of the gravity center of the electric carrying test vehicle 100 positioned in the elevator, namely, the gravity center of the electric carrying test vehicle 100 can be adjusted to be consistent with the gravity center of the elevator by moving the electric carrying test vehicle 100 in the elevator in a small range, thereby facilitating the test of the elevator.
