Abstract
The utility model discloses a fixed crane with a vertical column and a rotary arm. The utility model is characterized in that a set of fixed pulleys [13] are arranged at the lower part of a horizontal travel mechanism [8] which is on a cross beam [5], and a crane pulley block can be formed by the fixed pulleys which are concatenated with a hook assembly [7] through a steel cable [14]. The fixed end of the steel cable can also be concatenated with a tensile sensor [12], so that the display and the control of crane moments can be realized. Under the premise of the same structural parameters with an original crane, the utility model has the advantage that the crane amount and the lifting height are greatly enhanced.
Description
The utility model relates to weight-lifting equipment, particularly the vertical columns turning crane.
The revolving jib crane of prior art generally is an installation electric block below dolly, as promoting power.Its shortcoming be electric block from great, limited and effectively played heavy load, the reel size of electric block self is bigger, has taken effectively room for promotion of part.
Deficiency at above has proposed the purpose of this utility model, designs a kind of vertical columns turning crane of new construction.(hoisting capacity is not more than 3 tons)
The purpose of this utility model is to realize like this.Have fixing single column, the minor axis neck of the crossbeam of I-shaped cross-section is being supported by rotation support mechanism in column upper end, is a spiral arm in work one side of crossbeam near the position of column, and the lower end of this spiral arm is an electrically operated rotating mechanism.Also have an electronic horizontal running mechanism on the crossbeam, a buting iron is arranged at its external part head.The non-working side of crossbeam is a workplatform that electric box and lifting winch structure are installed.The steel rope of lifting winch structure connects the suspension hook assembly through one group of fixed pulley on the horizontal running mechanism below crossbeam.The end of steel rope is fixed on the attachment point of the external part of crossbeam.The movable pulley on the suspension hook and the fixed pulley of traveling gear and steel rope constitute a simple assembly pulley.The position that power controling box and display control switch are located at the following easy to operate of column and observe.
For hoisting crane of the present utility model is had than the failure-free in-use performance, between the attachment point of the end of steel rope and the external part of crossbeam, be connected in series a pulling force sensor.This sensor is connected with display control switch on being contained in column by lead, to show load and to have limited lifting moment.
The utility model has the advantages that under the precondition of the structure of column that does not change original hoisting crane and crossbeam, effectively hoisting depth has increased (near the height of an electric block), effectively hoisting capacity has increased (near the quality of an electric block).And the lifting winch structure is located at the nonclient area of the crossbeam on the column, and the quality of electrical motor and winch and electric box can balance part hoisting moment.
The following drawings explanation, accompanying drawing is a structural representation of the present utility model, in the accompanying drawings, sequence number 1 vertical columns, 2 electric boxs, 3 lifting winch structures, 4 spiral arms, 5 crossbeams, 6 rotating mechanisms, 7 suspension hook assemblies, 8 horizontal running mechanisms, 9 buting iron, 10 display control switchs, 11 rotation support mechanisms, 12 pulling force sensors, 13 fixed pulleys, 14 steel ropes, 15 power controling boxs.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Column ［ 1 ］ is fixed by design attitude, the rotation support mechanism ［ 11 ］ that the upper end of column is formed by one group of bearing is supporting the minor axis neck on the crossbeam ［ 5 ］, active side at crossbeam has a spiral arm ［ 4 ］ near the column place, an electrically operated rotating mechanism ［ 6 ］ is arranged in the lower end of spiral arm, this mechanism cooperates with fixedly ring on the column by friction wheel, and the drive crossbeam rotates in a circumferential direction under the drive of electrical motor.Crossbeam is generally the I-shaped cross-section, non-working side at crossbeam is a workplatform, steel rope ［ 14 ］ on the reel of an electric box ［ 2 ］ and an electric hoist hoisting mechanism ［ 3 ］ hoisting mechanism is set on it below crossbeam, connect suspension hook assembly ［ 7 ］ through the fixed pulley ［ 13 ］ that is assemblied on the electronic horizontal running mechanism ［ 8 ］ on the crossbeam, through the pulley on the suspension hook assembly, on horizontal running mechanism another fixed pulley ［ 13 ］ again, the end of steel rope is fixed on the attachment point of external part of crossbeam, also has a buting iron ［ 9 ］ in this fixed point, with the limit levels traveling gear, when moving, it is unlikely to the accident that exceeds the maximum and move.
As shown in drawings, the end in steel rope ［ 14 ］, the pulling force sensor ［ 12 ］ of connecting, the signal of this sensor passes to the display control switch ［ 10 ］ that is contained on the column ［ 1 ］ through cable, has shown heavy lift.And connect with power controling box ［ 15 ］, the restriction hoisting crane play lifting moment.
Its working process is, when suspension hook ［ 7 ］ was sling weight, the hoisting of weight rotated by the driven by motor reel of lifting winch structure, and haulage cable ［ 14 ］ makes the suspension hook vertical lift.Walking in a horizontal state makes the walking in a horizontal state dolly do moving back and forth of horizontal direction on crossbeam by the motor drives of horizontal running mechanism ［ 8 ］ friction wheel on it, has realized the parallel motion of suspension hook and weight simultaneously.The rotation of crossbeam be the driven by motor of rotating mechanism ［ 6 ］ on it friction wheel and the set collar frictional transmission on the column, under the effect of spiral arm ［ 4 ］, make the minor axis neck of crossbeam ［ 5 ］ drive crossbeam and do circumferentially to rotate around the axle center of rotation support mechanism ［ 11 ］.
Claims (2)
1, a kind of have a vertical columns [1], rotation support mechanism [11], lifting winch structure [2], spiral arm [4], crossbeam [5], rotating mechanism [6], suspension hook assembly [7], horizontal running mechanism [8], the vertical columns turning crane of buting iron [9] is characterized in that one group fixed pulley [13] the serial connection suspension hook assembly [7] of the steel rope [14] of lifting winch structure [2] below crossbeam [5] below horizontal running mechanism [8].
2,, it is characterized in that the pulling force sensor ［ 12 ］ that is connected in series between the attachment point of external part of the end of said steel rope ［ 14 ］ and crossbeam ［ 5 ］ according to the described vertical columns turning crane of claim 1.
