Description

Technical Field

[0001] The utility model relates to the technical field of protection devices, in particular to a safety anti-collision protection device for a gantry crane. Background Art

[0002] A protective device is a device used to protect equipment, systems or personnel from potential danger or damage. It can adopt a variety of different forms and technologies according to different application scenarios and needs, and is widely used in various fields, including electricity, water conservancy, transportation, petroleum, chemical industry, coal, metallurgy and other industries.

[0003] In order to prevent the lifting trolleys from colliding with each other or hitting the surfaces of the support beams at both ends, existing gantry cranes usually use springs for shock absorption protection. However, the protection effect of a single spring is poor and cannot effectively reduce the impact force during a collision. At the same time, it is also unable to effectively prevent the occurrence of collision accidents in a timely manner, resulting in the lifting trolley being damaged due to multiple collisions. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the lifting trolley is easily damaged due to poor protection effect when the above-mentioned equipment is in use, and thus a safety anti-collision protection device for a gantry crane is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a gantry crane safety anti-collision protection device, comprising a main body mechanism, a speed reduction mechanism is fixedly installed on one side of the outer wall of the main body mechanism;

[0006] The main body mechanism includes two base frames, a support beam is fixedly installed between the tops of the two base frames, a lifting trolley is slidably connected to the inner wall of the support beam, a rangefinder is fixedly installed on the top of the lifting trolley, a camera is fixedly installed on the top of the lifting trolley, four sliding grooves are opened on the outer wall of the lifting trolley, sliders are movably embedded in the inner walls of the four sliding grooves, springs are fixedly installed at the bottom of the four sliders, and the bottoms of the four springs are fixedly connected to the bottom of the inner wall of the sliding groove, scrapers are fixedly installed on one side of the outer wall of the four sliders, and the outer walls of the four scrapers are in contact with the inner wall of the support beam.

[0007] Preferably, two outer shells are fixedly mounted on the outer surface wall of the lifting trolley, and pistons are movably inserted into the inner surfaces of the two outer shells.

[0008] Preferably, a group of dampers are fixedly mounted on one side of the outer walls of the two pistons, and a group of springs 2 are fixedly mounted on one side of the outer walls of the two pistons.

[0009] Preferably, a baffle is fixedly installed between the outer walls of the two groups of springs 2, and the telescopic ends of the two groups of dampers are fixedly connected to one side of the outer wall of the baffle.

[0010] Preferably, the speed reduction mechanism comprises two mounting plates, one side of the outer wall of the two mounting plates is provided with a circular hole, and one side of the outer wall of the two mounting plates is fixedly mounted with a cylinder.

[0011] Preferably, a moving rod is provided at the output end of the two cylinders, and the inner walls of the two circular holes are movably inserted with the outer walls of the moving rod, and a brake pad is fixedly installed on one side of the outer walls of the two moving rods.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, under the action of the main mechanism and the deceleration mechanism, the rangefinder and the camera can observe the situation around the lifting trolley. When the lifting trolley encounters an obstacle, the cylinder will drive the brake pad to move and clamp the support beam, thereby improving the braking effect and avoiding the collision of the lifting trolley, which will cause damage to internal parts and reduce the service life of the device.

[0015] 2. In the utility model, under the action of the main mechanism, when the lifting trolley moves, the pollutants inside the slideway will be scraped off by the scraper, so as to keep the slideway clean and smooth, thereby improving the operation efficiency and stability of the lifting trolley.

[0024] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0026] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a safety anti-collision protection device for a gantry crane, comprising a main body mechanism 1, and a speed reduction mechanism 2 is fixedly installed on one side of the outer wall of the main body mechanism 1;

[0027] The main body mechanism 1 includes two base frames 101, a support beam 102 is fixedly installed between the tops of the two base frames 101, a lifting trolley 103 is slidably connected to the inner surface wall of the support beam 102, a rangefinder 104 is fixedly installed on the top of the lifting trolley 103, a camera 105 is fixedly installed on the top of the lifting trolley 103, four slide grooves 106 are opened on the outer wall of the lifting trolley 103, and sliders 107 are movably embedded in the inner surface walls of the four slide grooves 106, and springs 108 are fixedly installed at the bottom of the four sliders 107, and the bottoms of the four springs 108 are fixedly connected to the bottom of the inner wall of the slide groove 106. A scraper 109 is fixedly installed on one side of the outer wall of 107, and the outer walls of the four scrapers 109 are in contact with the inner wall of the support beam 102. Two outer shells 110 are fixedly installed on the outer wall of the lifting trolley 103, and pistons 111 are movably inserted in the inner walls of the two outer shells 110. A group of dampers 112 is fixedly installed on one side of the outer walls of the two pistons 111. A group of springs 113 is fixedly installed on one side of the outer walls of the two pistons 111. A baffle 114 is fixedly installed between the outer walls of the two groups of springs 113, and the telescopic ends of the two groups of dampers 112 are fixedly connected to one side of the outer wall of the baffle 114.

[0028] The effect achieved by the entire embodiment 1 is that when the lifting trolley 103 is moving, the camera 105 and the rangefinder 104 on the top can be rotated to one side of the moving direction to detect the situation and distance between the lifting trolley 103 and other obstacles, thereby reducing the probability of collision of the lifting trolley 103 and thus reducing the collision frequency. When the lifting trolley 103 collides, the baffle 114 will be forced to shrink, squeezing a set of dampers 112 and spring 113 at the rear, so that the piston 111 is pushed to move inside the housing 110. , compresses the air inside the shell 110, and cooperates with the damper 112 and the spring 113 to greatly reduce the impact force on the lifting trolley 103, thereby reducing the damage rate and maintenance cost of the equipment. When the lifting trolley 103 moves, it will drive the scraper 109 to scrape up the pollutants inside the moving groove to prevent the pollutants from affecting the stability and efficiency of the lifting trolley 103. When the scraper 109 encounters some pollutants that are difficult to remove, it can pull the spring 108 to rise, thereby preventing the scraper 109 from being damaged.

[0029] Embodiment 2, as Figure 2-Figure 5 As shown, the reduction mechanism 2 includes two mounting plates 201, and circular holes 202 are opened on one side of the outer walls of the two mounting plates 201, and cylinders 203 are fixedly installed on one side of the outer walls of the two mounting plates 201. Moving rods 204 are provided at the output ends of the two cylinders 203, and the inner walls of the two circular holes 202 are movably inserted into the outer walls of the moving rods 204, and brake pads 205 are fixedly installed on one side of the outer walls of the two moving rods 204, and the outer walls of the lifting trolley 103 are fixedly connected to the outer walls of the two mounting plates 201.

[0030] The effect achieved by the entire embodiment 2 is that after the cylinder 203 is started, the brake pad 205 is driven to move through the moving rod 204, so that it contacts the outer wall of the support beam 102, quickly and effectively stops the movement of the lifting trolley 103, and reduces the occurrence of collision events.

[0031] Working principle: The lifting trolley 103 can slide freely on the surface of the support beam 102. When the lifting trolley 103 is moving, the camera 105 on the top can observe the actual situation on one side of the moving direction to prevent the lifting trolley 103 from colliding. The rangefinder 104 can detect the distance between it and the two sides of the support beam 102 or other lifting trolleys 103. When the lifting trolley 103 detects that a collision is about to occur, it will stop moving on the surface of the support beam 102. At this time, the cylinder 203 starts, driving the moving rod 204 to move forward inside the circular hole 202, thereby pushing the brake pad 205 to start moving. When the brake pad 205 moves, it will contact the outer wall of the support beam 102, thereby improving the braking effect and speed of the lifting trolley 103. When the lifting trolley 103 collides , the obstacle begins to squeeze the baffle 114, causing the baffle 114 to move backward, and then the baffle 114 begins to squeeze a group of dampers 112 and spring 113 at the rear, and a group of dampers 112 and spring 113 begin to shrink to absorb the impact force during the collision. At the same time, a group of dampers 112 and spring 113 are also driven backward by the impact force, causing the piston 111 to move inside the shell 110, thereby compressing the air inside the shell 110 and further absorbing the impact force. When the lifting trolley 103 moves on the surface of the support beam 102, it will drive the scraper 109 on the moving side to move inside the moving groove, thereby scraping up the pollutants accumulated inside the moving groove to prevent these pollutants from hindering the advancement of the lifting trolley 103 or entering the inside of the lifting trolley 103 to cause internal parts to malfunction.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
