Description
Technical Field
[0001] This utility model relates to the field of transfer equipment technology, and more specifically, to a transport trolley for assembling and disassembling a safety fence. Background Technology
[0002] Currently, the main methods for moving isolation fences are: one is to use manual labor. Since the isolation fences have a certain weight, manual moving is not only inefficient, but also physically demanding for workers during long-distance transport; the other method is to use flatbed carts. However, using a common flatbed cart can only move a maximum of 6 isolation fences at a time, which is inefficient and the fences are prone to falling during transport.
[0003] To address the aforementioned issues, patent document publication number CN215590791U describes a barrier transport trolley, which includes a lower plate with casters at the bottom and an upper plate above it. The upper plate is connected to the lower plate via a connecting frame, which is also connected to a handrail. The upper plate has several openings for the barrier bars to pass through.
[0004] However, it still has some drawbacks in actual use. For example, the device can ensure that the isolation fence will not sway back and forth during transportation. Isolation fences can also be placed on the upper plate to achieve double-layer placement of isolation fences, improve work efficiency and reduce the labor intensity of workers. However, the device itself lacks a lateral limiting structure and only relies on the guardrail to fix the fence placed on the upper layer. During the transportation process, the fence is still easy to tip over due to the unstable center of gravity. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a transport trolley for a safety fence that is easy to assemble and disassemble, so as to solve the problem that the prior art device itself lacks a lateral limiting device and the upper fence is prone to tipping over due to instability of the center of gravity.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a trolley for arranging and transporting safety fences that is easy to assemble and disassemble, including a lower shelf, a connecting frame on the top of the lower shelf, a guardrail on one side of the connecting frame, and the trolley also includes...
[0007] A socket, which is slidably mounted on the surface of the guardrail;
[0008] A connecting ring is fixedly installed on the surface of the socket. An mounting sleeve is rotatably installed on the inner ring of the connecting ring. The mounting sleeve is configured as a hollow structure, and the inner wall of the mounting sleeve is in contact with the surface of the socket.
[0009] A fixed column, the bottom of which is fixedly connected to the surface of the mounting sleeve, and a movable column is movably installed on the inner wall of the fixed column;
[0010] A connecting seat is disposed on one side of the top of the movable column, and a limiting column is fixedly connected to the side of the connecting seat opposite to the movable column.
[0011] The device also includes a fixing rod, an extension post, a snap-fit plate, and a bonding pad. The fixing rod is disposed opposite to each other on the surface of the limiting post. The extension post is slidably mounted on the surface of the fixing rod. The snap-fit plate is slidably mounted on the side of the extension post near the fixing rod. The snap-fit plate is configured with an L-shaped structure. The bottom of the snap-fit plate abuts against the surface of the fixing rod. The bonding pads are disposed on the surfaces of the limiting post and the extension post respectively. The bonding pads are configured with a rough surface structure.
[0012] It also includes a fastening assembly, which is disposed on the outside of the socket.
[0013] The fastening assembly includes a second connecting frame, a screw, a mounting plate, and abutment posts. The screw is fixedly installed on the outside of the connecting ring and rotatably installed on the surface of the second connecting frame. The mounting plate is threaded onto the surface of the screw, and the side of the mounting plate is in contact with the side of the second connecting frame opposite to the connecting ring. The abutment posts are arranged opposite each other on the surface of the mounting plate, and the surface of the abutment posts is in contact with the inner wall of the socket. One end of the abutment post opposite to the mounting plate passes through the socket and abuts against the surface of the guardrail.
[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:
[0015] In the above scheme, when the fence is placed on top of the lower plate, the movable column is moved inside the fixed column, so that the vertical position of the limiting column can be adjusted according to the height specification of the fence. Then, the snap plate set on the surface of the extension column is moved vertically upward, so that the bottom of the snap plate separates from the groove on the surface of the fixed rod. At this time, the extension column can be moved horizontally along the fixed rod, thereby extending on the basis of the limiting column. Then, the snap plate is reset so that it abuts against the fixed rod to fix the extension column after the extension movement. At this time, the fixed column can be deflected at a certain angle around the mounting sleeve so that the limiting column contacts the surface of the fence on the upper layer, that is, the lateral limiting of the fence is achieved, preventing the fence from tipping over due to instability of the center of gravity during transportation, thereby improving the practicality of the device.
[0016] By moving the socket horizontally on the surface of the guardrail, the limiting post can be adjusted to a certain horizontal position according to the placement of the guardrail. After adjustment, by rotating the screw on the second surface of the connecting frame, the mounting plate installed on the screw surface can be moved horizontally, thereby causing one end of the abutment post relative to the mounting plate to abut against the surface of the guardrail. The friction generated by the abutment fixes the socket, preventing the socket from accidentally loosening and affecting the limiting post's position on the guardrail. Attached Figure Description

[0024] Socket 4 is slidably installed on the surface of guardrail 3;
[0025] The connecting ring 5 is fixedly installed on the surface of the socket 4. The inner ring of the connecting ring 5 is rotatably installed with the mounting sleeve 6. The mounting sleeve 6 is set as a hollow structure. The inner wall of the mounting sleeve 6 is in contact with the surface of the socket 4. The part of the mounting sleeve 6 that contacts the inner ring of the connecting ring 5 is set as a rough surface structure, so that the fixing post 7 can remain fixed after deflecting around the mounting sleeve 6 at a certain angle. Thus, the limiting post 10 and the bonding pad 14 can be firmly attached to the outside of the fence to limit its movement.
[0026] The fixed post 7 is fixedly connected to the surface of the mounting sleeve 6 at its bottom. The movable post 8 is movably installed on the inner wall of the fixed post 7. The movable post 8 and the fixed post 7 are connected by friction. The friction generated between the two can fix the position of the movable post 8 after it moves vertically, so as to prevent the movable post 8 from falling accidentally during the process of the limiting post 10 limiting the fence.
[0027] Connecting seat 9 is located on one side of the top of the movable column 8, and a limiting column 10 is fixedly connected to the side of the surface of the connecting seat 9 opposite to the movable column 8.
[0028] The system also includes a fixing rod 11, an extension post 12, a snap-fit plate 13, and a fitting pad 14. The fixing rod 11 is disposed opposite to each other on the surface of the limiting post 10. The extension post 12 is slidably mounted on the surface of the fixing rod 11. The snap-fit plate 13 is slidably mounted on the side of the extension post 12 near the fixing rod 11. The snap-fit plate 13 is configured with an L-shaped structure, and its bottom abuts against the surface of the fixing rod 11. The fitting pad 14 is disposed on the surfaces of the limiting post 10 and the extension post 12 respectively. The fitting pad 14 is configured with a rough surface structure. Through the snap-fit plate 13, its bottom can abut against the groove opened on the top of the fixing rod 11. The friction generated by the abutment can fix the extension post 12 after horizontal movement, preventing the extension post 12 from accidentally retracting after extension.
[0029] It also includes a fastening component 15, which is disposed on the outside of the socket 4.
[0030] The fastening assembly 15 includes a connecting frame 151, a screw 152, a mounting plate 153, and an abutment post 154. The screw 152 is fixedly installed on the outside of the connecting ring 5 and rotatably installed on the surface of the connecting frame 151. The mounting plate 153 is threaded onto the surface of the screw 152. The side of the mounting plate 153 is in contact with the side of the connecting frame 151 opposite to the connecting ring 5. The abutment post 154 is disposed on both sides of the surface of the mounting plate 153. The surface of the abutment post 154 is in contact with the inner wall of the socket 4, and one end of the abutment post 154 opposite to the mounting plate 153 passes through the socket 4 and abuts against the surface of the guardrail 3.
[0031] The working process of this utility model is as follows: When the fence is placed on the top of the lower plate 1, the movable column 8 is moved inside the fixed column 7 so that the vertical position of the limiting column 10 can be adjusted according to the height specification of the fence. Then, the snap-fit plate 13 set on the surface of the extension column 12 is moved vertically upward so that the bottom of the snap-fit plate 13 is separated from the groove on the surface of the fixed rod 11. At this time, the extension column 12 can be moved horizontally along the fixed rod 11 to extend on the basis of the limiting column 10. Then, the snap-fit plate 13 is reset so that it abuts against the fixed rod 11 to fix the extended column 12 after the extension movement. At this time, the fixed column 7 can be deflected at a certain angle around the mounting sleeve 6 so that the limiting column 10 contacts the surface of the fence on the upper layer.
