Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for loading foam glass onto vehicles, specifically to a safety protection device for loading foam glass onto vehicles. Background Technology

[0002] Foam glass is a lightweight, high-strength building and decorative material with superior thermal insulation (cold insulation), sound absorption, moisture resistance, and fire resistance. It is an inorganic non-metallic glass material made from crushed glass, foaming agent, modified additives, and foaming accelerators, which are finely crushed and uniformly mixed, then melted at high temperature, foamed, and annealed. After the foam glass is processed, it needs to be packaged and loaded onto trucks for transportation. The packaged foam glass is in rectangular blocks and then loaded onto flatbed trucks for transport.

[0003] During loading, workers stack foam glass in a stepped manner from the front of the truck to the back, layer by layer until the highest point. Because the foam glass blocks are quite high after loading and there is no protection around the flatbed truck, workers have to step on the foam glass to load and unload, which poses a significant safety hazard. Furthermore, the safety device needs to be able to secure itself when pulling workers. Therefore, it is necessary to provide a safety protection device for loading foam glass. Utility Model Content

[0004] The purpose of this utility model is to provide a safety protection device for loading foam glass onto trucks, so as to solve the safety hazard of workers falling when loading foam glass onto trucks, as well as the problem of fixing the protection device.

A support spring is fixedly installed between the brake rod and the upper mounting seat. Positioning pins are slidably installed on the two upper mounting seats. Positioning springs are fixedly installed between the positioning pins and the mounting seats. A positioning pad is fixedly installed at one end of the brake rod, and several positioning grooves are opened side by side in the middle of the brake rod.

[0010] Preferably, a handle is fixedly installed at the upper end of the brake lever, and the positioning pad is composed of a rubber pad with high frictional resistance.

[0011] Preferably, the positioning pin is adapted to a plurality of positioning slots, and the support spring is located inside the mounting base.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] Combination Figures 1-3 A safety protection device for loading foam glass includes two No. 1 wheel frames 1, with a fixed frame 2 fixedly installed between the two No. 1 wheel frames 1, and a protective mechanism 3 installed on the two No. 1 wheel frames 1. The protective mechanism 3 includes two No. 2 wheel frames 301 and two No. 3 wheel frames 302. A hanging wheel 303 is fixedly installed on the upper part of each of the two No. 3 wheel frames 302, and two double sliders 304 are slidably installed side by side on both sides of each of the two No. 2 wheel frames 301. Two single sliders 305 are slidably installed side by side on both sides of each of the two No. 1 wheel frames 1 and the two No. 3 wheel frames 302. A first lever 306 and a second lever 307 are rotatably installed between adjacent double sliders 304 and single sliders 305.

[0021] Wheel frame 1, wheel frame 2 301, and wheel frame 302 are all composed of U-shaped rods and two rollers. The rollers allow the device to move flexibly. The fixing frame 2 consists of two cross plates, which can increase the stability of the two wheel frames 1 and prevent the device from tipping over. The first winch 306 and the second winch 307 are of the same length and are rotatably mounted at their midpoints. The hanging wheel 303 is fixedly installed in the middle of wheel frame 302, and a fixed folding rod is installed on the lower side of the hanging wheel 303. The fixed folding rod is used to fix the safety rope. The device connects wheel frame 1, wheel frame 2, and wheel frame 302 via double slider 304 and single slider 305, first winch 306, and second winch 307. This allows wheel frame 302 and wheel frame 2 to stretch or contract relative to wheel frame 1, enabling the device to be flexibly deployed and placed on the flatbed truck. The rollers on both sides of the device are located on the sides of the flatbed truck. In use, the device is connected to the safety rope on the employee via hanging wheel 303, and wheel frame 302 can be moved according to loading and unloading needs, providing effective safety protection for the employee and preventing falls from heights. Example 2

[0022] See Figure 4 and Figure 5 A braking mechanism 4 is provided on the second wheel frame 301. The braking mechanism 4 includes four mounting seats 401, which are fixedly installed side by side on both sides of the second wheel frame 301. A brake rod 402 is slidably installed through the upper and lower mounting seats 401. A support spring 403 is fixedly installed between the brake rod 402 and the upper mounting seat 401. A positioning pin 404 is slidably installed on each of the two upper mounting seats 401. A positioning spring 405 is fixedly installed between the positioning pin 404 and the mounting seat 401. A positioning pad 406 is fixedly installed at one end of the brake rod 402, and several positioning grooves 407 are opened side by side in the middle of the brake rod 402.

[0023] A handle is fixedly installed on the upper end of the brake lever 402. The positioning pad 406 is composed of a rubber pad with high frictional resistance. The positioning pin 404 is adapted to several positioning grooves 407. The support spring 403 is located inside the mounting base 401. In use, by applying external force to pull the positioning pin 404, it is disengaged from the positioning groove 407, thus releasing the restriction of the positioning pin 404 on the brake lever 402. At this time, the positioning pad 406 can be pressed against the ground by pressing the brake lever 402. At this time, the positioning pin 404 is embedded into the positioning groove 407 under the action of the positioning spring 405, thus fixing the brake lever 402. Under the action of the friction between the positioning pad 406 and the ground, the device will be unable to move.

[0024] In actual operation, the first wheel frame 1, the second wheel frame 301, and the third wheel frame 302 are connected by the double slider 304 and the single slider 305, the first winch 306, and the second winch 307. This allows the third wheel frame 302 and the second wheel frame 301 to be stretched or contracted relative to the first wheel frame 1, so that the device can be flexibly deployed on the flatbed truck. When in use, the hanging wheel 303 is connected to the safety rope on the employee, and the third wheel frame 302 can be moved according to the loading and unloading requirements, which can provide effective safety protection for the employee and prevent the employee from falling from a height. By applying external force to pull the positioning pin 404 out of the positioning groove 407, the restriction of the positioning pin 404 on the brake rod 402 can be released. At this time, the positioning pad 406 can be pressed against the ground by pressing the brake rod 402. At this time, the positioning pin 404 is embedded in the positioning groove 407 under the action of the positioning spring 405, thus fixing the brake rod 402. Under the action of the friction between the positioning pad 406 and the ground, the device will be unable to move.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
