Description

Technical Field

[0001] This utility model relates to the field of cement block transportation technology, specifically a building cement block loading and unloading device. Background Technology

[0002] Building cement blocks are a type of building material made from ordinary concrete materials such as cement, sand, and stone. They are mainly used for the construction of interior walls and enclosures of buildings. They have advantages such as light weight, good thermal performance, and strong vibration resistance, and are widely used in non-load-bearing walls, infill walls, partition walls, and exterior walls.

[0003] Publication number CN214191218U discloses a method for loading and unloading building cement blocks. The block is clamped by two sets of clamps, and the position of the clamps can be fixed. This eliminates the need for workers to continuously clamp the blocks during loading and unloading, effectively reducing the labor intensity of workers. However, this patent still has the following problems in practical use:

[0004] When fixing cement blocks, the clamps on both sides swing, which means that the clamps cannot fit tightly against the sides of the cement block and only limit the sides of the cement block. This makes it very likely that the cement block will shift or even slip during transportation, thus failing to guarantee the stability of the cement block during transportation.

[0005] A building cement block loading and unloading device is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a building cement block loading and unloading device to solve the problem mentioned in the background art that when cement blocks are fixed, the clamps on both sides swing, which causes the clamps on both sides to be unable to fit tightly against the sides of the cement block, and only limits the sides of the cement block. This may cause the cement block to shift or even slip during transportation, thus failing to guarantee the stability of the cement block transportation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a building cement block loading and unloading device, including a connecting plate;

[0008] Also includes:

[0009] The connecting plate is provided with a loading and unloading assembly, which includes a connecting frame. A limit rod is fixedly connected to the inner side of the connecting frame, and a sliding plate is slidably connected to the outer side of the limit rod. A first spring is symmetrically fixed between the sliding plate and the connecting frame.

[0010] Among them, the bottom of the skateboard is symmetrically fixed with movable rods, and the movable rods are slidably connected to the connecting plate and pass through the connecting plate, and the bottom of the movable rods is fixedly connected with a connecting block;

[0011] The connecting block has symmetrical rotating rods on both sides, and the bottom of the connecting plate is symmetrically fixed with limit strips, and the limit strips are slidably connected to clamps on the outside.

[0012] Preferably, a second spring is fixedly connected between the clamping plate and the limiting strip, and the rotating rod is rotatably connected to the clamping plate.

[0013] Preferably, the clamping plate has a sliding groove inside, and the rotating rod slides inside the sliding groove with the rotating shaft of the clamping plate.

[0014] Preferably, the limiting strip is U-shaped.

[0015] Preferably, a limiting component is provided on one side of the clamping plate. The limiting component includes a mounting block, and two mounting blocks are symmetrically fixed. The mounting blocks are fixedly connected to the clamping plate, and a third spring is fixedly connected to the bottom of the mounting block. A clamping block is fixedly connected to the bottom of the third spring.

[0016] Preferably, an inclined plate is fixedly connected to one side of the clamping block, and a limit block is fixedly connected to the other side of the clamping block.

[0017] Preferably, the clamping plate has a sliding groove inside, and the limiting block slides inside the sliding groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this building cement block loading and unloading device can not only flatten and fix the sides of the cement block during the installation and transportation of cement blocks, but also fix the top and bottom of the cement block, thereby making the fixing effect of the cement block better. The specific details are as follows:

[0019] 1. Place the cement blocks to be loaded and unloaded on a pad, ensuring the pad's width is less than the block's width. The worker holds the device and places it on the outside of the cement block, with the lower middle part of their palm pressing against the top of the connecting frame. Pulling the sliding plate upwards compresses the first spring, causing the moving rod to move upwards. This, in turn, moves the connecting block upwards, causing the rotating rods on both sides to rotate. The rotation of these rods changes the position of their ends, causing the clamping plates on both sides to move in opposite directions. These clamping plates then fix the cement block in place, improving the stability of the cement block during transport.

[0020] 2. As the clamping plate moves, the inclined plate will first contact the cement block. As the clamping plate continues to move, the inclined plate will be compressed and its position will change continuously until the clamping block contacts the cement block. Secondly, when the clamping block contacts the cement block, the third spring is just compressed to its limit, so that the upper and lower sides of the cement block can be fixed before the cement block is transported, thereby further improving the stability of the fixed transportation of the cement block.

[0027] 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.

[0028] Please see Figure 1 - Figure 5 The present invention provides the following technical solution:

[0029] A building cement block loading and unloading device includes a connecting plate 1; the connecting plate 1 is provided with a loading and unloading assembly 2, the loading and unloading assembly 2 includes a connecting frame 201, and a limiting rod 202 is fixedly connected to the inner side of the connecting frame 201, and a sliding plate 203 is slidably connected to the outer side of the limiting rod 202, and a first spring 205 is symmetrically fixed between the sliding plate 203 and the connecting frame 201; wherein, a moving rod 206 is symmetrically fixed to the bottom of the sliding plate 203, and the moving rod 206 is slidably connected to and passes through the connecting plate 1, and a connecting block 207 is fixedly connected to the bottom of the moving rod 206; wherein, rotating rods 208 are symmetrically rotated on both sides of the connecting block 207, and a limiting strip 209 is symmetrically fixed to the bottom of the connecting plate 1, and a clamping plate 210 is slidably connected to the outer side of the limiting strip 209, such as Figure 1 , 2 As shown in Figures 3 and 5, when the finger pulls the slide plate 203 upward, the slide plate 203 compresses the first spring 205. As the slide plate 203 rises, it drives the moving rod 206 upward. The moving rod 206 then drives the connecting block 207 upward, which in turn drives the rotating rods 208 on both sides to rotate. Because the positions of the two ends of the rotating rods 208 change during rotation, in conjunction with the rebound of the second spring 211, the clamping plates 210 on both sides move in opposite directions. The clamping plates 210 then fix the cement block on both sides, thereby improving the stability of the cement block during transport. The clamping plates 210 and the limiting strip 209... A second spring 211 is fixedly connected between them. Secondly, the elasticity of the first spring 205 and the second spring 211 needs to be set according to the actual situation. Because during transportation, the porter needs to pull the slide plate 203 with his fingers to stabilize the cement block. Therefore, the manufacturing of the elasticity of the first spring 205 and the second spring 211 is particularly important to avoid excessive elasticity, which would make the porter more tired during transportation. The rotating rod 208 is rotatably connected to the clamping plate 210. The clamping plate 210 has a groove 212 inside, and the rotating rod 208 and the rotating shaft of the clamping plate 210 slide inside the groove 212. The limiting strip 209 is U-shaped.

[0030] A limiting component 3 is provided on one side of the clamping plate 210. The limiting component 3 includes two mounting blocks 301, which are symmetrically fixed and fixedly connected to the clamping plate 210. A third spring 302 is fixedly connected to the bottom of the mounting block 301, and a clamping block 303 is fixedly connected to the bottom of the third spring 302. An inclined plate 306 is fixedly connected to one side of the clamping block 303, and a limiting block 305 is fixedly connected to the other side of the clamping block 303. A sliding groove 304 is provided inside the clamping plate 210. The sliding groove 304 and the limiting block 305 limit the clamping block 303, so that the clamping block 303 can only move linearly. Figure 4 , 5As shown, while the clamping plate 210 moves, the inclined plate 306 will first contact the cement block. As the clamping plate 210 moves continuously, the inclined plate 306 will be compressed and its position will change continuously until the clamping block 303 contacts the cement block. Secondly, when the clamping block 303 contacts the cement block, the third spring 302 is just compressed to the extreme, so that the upper and lower sides of the cement block can be fixed before the cement block is transported, thereby further improving the stability of the fixed transport of the cement block. The limiting block 305 slides inside the sliding groove 304.

[0031] Working principle: Before using this type of building cement block loading and unloading device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5 As shown, firstly, the cement blocks to be loaded and unloaded are placed on a pad, the width of which should be smaller than the width of the cement blocks. Then, the worker holds the device and places it on the outside of the cement blocks, with the lower middle part of their palm pressing on the top of the connecting frame 201. The worker then pulls the sliding plate 203 upwards, compressing the first spring 205. As the sliding plate 203 rises, it drives the moving rod 206 upwards. The moving rod 206 then drives the connecting block 207 upwards, which in turn drives the rotating rods 2 on both sides. When the rotating rod 208 rotates, the positions of the two ends change. Therefore, in conjunction with the rebound of the second spring 211, the clamping plates 210 on both sides move towards each other. Then, the clamping plates 210 on both sides will move and fix the cement block on both sides, thereby improving the firmness of the cement block for fixed transportation. Secondly, when it is necessary to remove the cement block, simply release the sliding plate 203. At this time, the first spring 205 will spring, thereby driving the sliding plate 203 to reset, thereby driving the above-mentioned components to run in the opposite direction, and thus the cement block can be released, thereby realizing the disassembly and use of the cement block.

[0032] As the clamping plate 210 moves, the inclined plate 306 will first come into contact with the cement block. As the clamping plate 210 continues to move, the inclined plate 306 will be compressed and its position will change continuously until the clamping block 303 comes into contact with the cement block. Then, when the clamping block 303 comes into contact with the cement block, the third spring 302 is just compressed to its limit, so that the upper and lower sides of the cement block can be fixed before the cement block is transported, thereby further improving the stability of the fixed transport of the cement block.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
