Description

Technical Field

[0001] The invention relates to a special transport rack for a small standard test engine and a transport method, belonging to the technical field of solid rocket engine charge. Background Art

[0002] After the solid rocket motor is loaded with propellant, in order to characterize the burning rate data of the full-size engine, a small standard test engine will be randomly added when the full-size engine is loaded with propellant. The small standard test engine will be used to characterize and predict the full-size engine.

[0003] After the small standard test engine is charged, it enters the vulcanization room with the charging tooling. Under the current production conditions, the small standard test engine with the charging tooling has a large aspect ratio, large ends, and a small middle. After the vulcanization, the small standard test engine needs to be transported to the demoulding and shaping workshop. Due to its unique structural characteristics, there are safety risks such as dumping during the transportation process. In addition, with the annual increase in the amount of charging tasks, the production volume of random small test engines has also increased. A large number of small test engines need to be transported every day, so the anti-dumping measures have been put forward for light and simple structures. Summary of the invention

[0004] The technical problem solved by the present invention is: in view of the problem that in the current prior art, there is a safety risk of dumping during the transportation process of small standard test engines, a special transportation rack and transportation method for small standard test engines are proposed.

[0005] The present invention solves the above technical problems by the following technical solutions:

[0006] A special transport rack for a small standard test engine, comprising side panels, transverse panels, joint panels and a folding structure, wherein:

[0007] The side panels are vertically installed on the edge of the transverse panel, and there are two of them, which are symmetrically arranged at the two ends of the edge of the transverse panel; the two plywood panels are vertically installed on the other two ends of the edge of the transverse panel; the plywood panels, the side panels and the transverse panel form a transfer frame, and the engine to be transferred is arranged in the transfer frame, and the transverse panel is provided with a storage hole for placing the engine to be transferred; the two ends of the folding structure are connected to the top edges of the two plywood panels, and when the engine to be transferred is placed or taken out, the folding structure is folded open; when the engine to be transferred is placed or taken out, the folding structure is folded closed.

[0008] The transfer rack frame structure is a group of two, and the side plates and the cross plates, the cross plates and the joint plates, and the side plates and the joint plates of the transfer rack frame are all fixedly connected by pins.

[0009] The folding structure comprises a folding upper plate and a folding lower plate, and hinge plates on both sides are connected by hinges to achieve unfolding and closing.

[0010] Transverse ribs are arranged at the contact positions between adjacent transfer rack frames. When the folding structure is folded and closed, flexible contact and sealing of the transfer process are achieved between adjacent transfer rack frames through the transverse ribs.

[0011] The folding upper plate and the folding lower plate are both provided with storage holes at the same positions as those provided on the horizontal plate to facilitate the placement of the engine to be transported.

[0012] The folding upper plate and the folding lower plate are folded inwards or outwards according to the placement or removal of the engine to be transported.

[0013] The contact positions of the folding upper plate, the folding lower plate and the side plate edges are provided with latches, and when the folding upper plate and the folding lower plate are in a horizontal position after the folding movement is completed, the position is fixed by the latches.

[0014] The side panels are each provided with handles to facilitate transportation, and there are four handles in total, which are symmetrically positioned.

[0015] When the engine to be transported is placed in the frame of the transport rack, the upper and lower ends of the engine to be transported are both located in the corresponding storage holes of the horizontal plate, the folding upper plate or the folding lower plate.

[0016] A transfer method implemented according to a dedicated transfer rack, comprising:

[0017] Assemble the special transfer rack structure, and place the special transfer rack structure on the external transfer tool by means of the handle;

[0018] Open the latch, fold the upper folding plate and the lower folding plate inward, and place the engine to be transported into the storage hole of the horizontal plate;

[0019] After folding the upper plate outward and folding the lower plate to a horizontal position, determine whether the upper and lower ends of the engine to be transferred are in the corresponding storage holes. After confirming that the engine to be transferred has been placed, close the latch to secure it.

[0020] The advantages of the present invention compared with the prior art are:

[0021] The present invention provides a special transfer rack and transfer method for a small standard test engine, which can solve the current safety risk of tipping over during the transfer process of a small standard test engine. By designing a stable special transfer rack structure, a stable transportation process of the small standard test engine with both upper and lower ends in circular holes is achieved. By fixing the two ends of the small standard test engine, the risk of tipping over of the small standard test engine is eliminated, thereby achieving the purpose of safe transfer of the standard test engine. At the same time, it has the advantages of being light and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
