Description

Technical Field

[0001] This application relates to the technical field of transfer devices, and particularly to a transfer cart. Background Art

[0002] The environmentally friendly gas-sealed ring network switchgear is a new type of green and environmentally friendly metal-sealed switchgear. When assembling, all conductive components (main switch, operating mechanism, etc.) need to be enclosed in a stainless steel gas tank, which can not only avoid the influence of external environmental factors, but also improve the operation reliability, enabling it to have the function of maintenance-free (or less maintenance), and at the same time meeting the requirements of miniaturization.

[0003] The main switch and the operating mechanism are usually assembled in different areas. When installing the main switch and the operating mechanism into the gas tank, a small cart is usually used for transfer. In the prior art, the small cart usually includes a base frame, a handle provided on the upper side edge of the base frame, and universal wheels provided at the four corner positions of the bottom side of the base frame; during transfer, the operating mechanism and the corresponding main switch are placed on the upper side of the base frame, and then the user pulls the handle on the base frame to drag the small cart to the assembly area of the gas tank for assembly.

[0004] However, although its original design is convenient for movement, when facing the main switch and the operating mechanism with irregular shapes and uneven surfaces, directly placing them flat for transfer is extremely likely to cause the equipment to be bumped and damaged, affecting subsequent use. In addition, limited by the area and load-bearing layout of the base frame, usually only 1 to 2 sets of equipment can be carried in a single transfer, with low efficiency and difficult to meet the actual needs of high-efficiency production. Summary of the Utility Model

[0005] The purpose of this application is to provide a transfer cart to solve the problems in the above related technologies that the small cart has low carrying efficiency and is likely to cause the irregularly carried items to be bumped and even damaged.

[0006] A transfer cart provided by this application adopts the following technical solutions:

[0007] A transfer cart includes a base frame, a plurality of universal wheels provided on the bottom side of the base frame, and a fixed frame for supporting products. A plurality of fixed notches for the products to be clamped and limited are separated by cross bars on the fixed frame; on the opposite two side surfaces of the base frame, guide plates parallel to each other are symmetrically fixed. The fixed frame is slidably arranged between the two guide plates, and a limiting member for sliding and limiting the fixed frame is provided on the guide plates.

[0008] By adopting the above technical solution, when transporting the operating mechanism and the corresponding main switch, the staff can first slide the fixing frame between the two guide plates, then use the limiting member to limit the fixing frame, and finally snap the operating mechanism and the corresponding main switch into the corresponding fixing notches on the fixing frame, which not only facilitates the assembly of the fixing frame, but also reduces the possibility of the operating mechanism and the main switch being bumped or damaged during transportation.

[0009] Optionally, a plurality of limiting rollers are rotatably arranged on the side surfaces of the two guide plates close to each other, and the plurality of limiting rollers are evenly distributed along the length direction of the guide plates. A fixing chute for the limiting rollers to be inserted and slide is formed on the side surface of the fixing frame facing the guide plates.

[0010] By adopting the above technical solution, due to the cooperative setting of the limiting rollers and the fixing chute, the sliding connection between the fixing frame and the guide plates is realized, and the possibility of the fixing frame being skewed or misaligned during the sliding relative to the guide plates is reduced.

[0011] Optionally, the limiting member is an adapter plate arranged at the end of the guide plate. A bending plate bent to one side is fixedly arranged on one side of the adapter plate, and a clamping plate bent to the same side is fixedly arranged on the other side of the adapter plate; a clamping groove for the clamping plate to be inserted is formed on the side surface of the guide plate far from the base frame; when the clamping plate is inserted into the clamping groove, one side of the bending plate can abut against the side surface of the end of the fixing frame.

[0012] By adopting the above technical solution, due to the setting of the limiting member, when the clamping plate is inserted into the clamping groove, one side of the bending plate can abut against the side surface of the end of the fixing frame; when the limit needs to be released, the clamping plate can be taken out of the clamping groove; it is convenient to lock the fixing frame and also convenient to unlock the fixing frame.

[0013] Optionally, a plurality of positioning plates are fixedly arranged on the side surface of the cross bar far from the base frame, and positioning notches are formed on the positioning plates.

[0014] By adopting the above technical solution, when the operating mechanism and the corresponding main switch are snapped into the fixing notches, the protruding parts on the product can be snapped into the positioning notches on the positioning plates, thereby further improving the stability of the product during transportation.

[0015] Optionally, a receiving frame is arranged above the base frame. A plurality of support rods for supporting the receiving frame are fixedly arranged on the upper surface of the base frame. A support frame for placing the product is arranged on the receiving frame, and a plurality of support notches for the product to be snapped and limited are separated by connecting rods on the support frame.

[0016] By adopting the above technical solution, due to the setting of the receiving frame and the support frame, the operating mechanism and the corresponding main switch can also be placed on the support frame, so that the transfer cart can transport more products at the same time and improve its service performance.

[0017] Optionally, guide rails that are parallel to each other are symmetrically and fixedly arranged on the receiving frame. The support frame is slidably arranged between the two guide rails, and a locking member for sliding and limiting the support frame is arranged on the receiving frame.

[0018] By adopting the above technical solution, due to the arrangement of the guide rails and the locking member, it is convenient to disassemble, assemble and fix the receiving frame, and it is convenient to remove the support frame from the receiving frame when needed.

[0019] Optionally, the locking member includes a locking plate rotatably arranged on the side surface of the receiving frame. A locking convex block is fixedly arranged on the side surface of the receiving frame, and a locking notch for inserting the locking convex block is formed on the locking plate. When the locking plate rotates upward to insert the locking convex block into the locking notch, one side of the locking plate protrudes from the upper side surface of the receiving frame and can abut against one side of the support frame.

[0020] By adopting the above technical solution, when the locking plate rotates upward to insert the locking convex block into the locking notch, one side of the locking plate protrudes from the upper side surface of the receiving frame and can abut against one side of the support frame, thereby realizing the limit of the support frame. When the locking plate rotates downward to disengage the locking convex block from the locking notch and rotate below the upper surface of the receiving frame, the sliding limit of the support frame is released at this time.

[0021] Optionally, a traction handle is fixedly arranged on one side edge of the base frame.

[0022] By adopting the above technical solution, it is convenient for the user to drive the whole transfer trolley to move by holding the traction handle.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:
