Description

Spacecraft supporting transfer trolley

Technical Field

The invention relates to a spacecraft supporting transfer trolley.

Background

The spacecraft is used as a special product, the length and the diameter of the spacecraft are different, the mass center of the spacecraft is different, the supporting length of the spacecraft is also different, the existing supporting transfer trolley is strong in specialization, and the supporting transfer requirements of different spacecrafts are difficult to meet.

Namely, the prior art solutions have the following disadvantages:

(1) only can support a spacecraft with the same diameter, is specialized and has no generalization characteristic.

(2) When the spacecraft is supported, the spacecraft cannot rotate radially and circumferentially, and a part of the supporting position is shielded, so that subsequent work cannot be carried out.

Disclosure of Invention

In the figure: the device comprises a support structure 1, a lead screw 2, a radial sliding assembly 3, a frame 4, a transfer wheel 5, an axial sliding assembly 6, a steering structure 7 and an axial fixing device 8.

Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

Example 1

A spacecraft support trolley as shown in figures 1 and 2, comprising a support structure 1; the supporting structures 1 are arranged on the radial sliding assemblies 3 in a left-right opposite pair and can move transversely, and the radial sliding assemblies 3 are arranged on the frame 4; the number of the support structures 1 is more than two pairs.

Based on embodiment 1, the radial slide assembly 3 is mounted on the axial slide assembly 6 and is movable in the front-rear direction along the axial slide assembly 6.

Example 3

Based on embodiment 1, a lead screw 2 is installed between the paired support structures 1.

Example 4

Based on embodiment 3, the center point between the pairs of support structures 1 is always located on the center perpendicular of the screw 2.

Example 5

Based on embodiment 2, the radial sliding component 3 is provided with an axial fixing device 8 at the bottom.

Example 6

Based on embodiment 1, the frame 4 is formed by welding square steel pipes.

Example 7

Based on example 1, the support structure 1 is provided with support wheels at the top.

Example 8

Based on embodiment 1, the supporting wheel is made of rubber.

Example 9

Based on above-mentioned embodiment, it is concrete, bearing structure comprises supporting wheel and support frame, and the supporting wheel adopts rubber to make, and is softer, and the supporting wheel and cylinder class spacecraft direct contact, rubber materials can avoid support in-process damage spacecraft surface, and bearing structure passes through the bolt and is connected with radial slider and slide rail.

Left-handed screw threads and right-handed screw threads are tapped by the screw rod, and when the screw rod rotates, the central distance of the left supporting structure and the right supporting structure can be increased and decreased, and the effect of finely adjusting the supporting height of the spacecraft can be achieved.

The radial slide block and the slide rail as well as the axial slide block and the slide rail are mainly used for connecting a support structure and changing the diameter and the support length of the support structure for supporting the spacecraft.

The frame is formed by welding square steel pipes, so that the integral bearing capacity of the vehicle is ensured, and the stability is high.

The structure of the transfer wheel mainly ensures the movement process of the vehicle.

The steering structure is a device for controlling the direction of movement of the vehicle.

The axial fixing device is used for fixing the axial position of the support structure.

In the using process, the distance between the two supporting wheels of the supporting structure can be adjusted by rotating the lead screw according to the diameter of the spacecraft until the diameter supporting requirement of the spacecraft is met. According to the supporting distance of the spacecraft, the axial sliding block at the lower end of the supporting structure slides to enable the supporting structure to move in the axial direction, at the moment, the distance between the two supporting structures is changed accordingly until the supporting requirement of the spacecraft is met, and after the condition is met, the supporting structure is fixed through the axial fixing device and cannot move. At the moment, the supporting transfer trolley meets the use requirement. In the process of pushing, pulling and supporting the transfer trolley, the running direction of the trolley can be changed by swinging the pull rod of the steering mechanism left and right, so that the steering effect is achieved.
