Description

Technical Field

[0001] This application relates to the field of elevator technology, and in particular to an anti-condensation elevator car for cold storage elevators. Background Technology

[0002] In real life, products that need to be refrigerated are usually stored in cold storage. In order to facilitate the transportation of products from cold storage to the ground, elevators need to be installed in cold storage. Staff put the packaged products into the elevator car, and the elevator car transports the products to different heights, which facilitates the transportation of refrigerated products.

[0003] Due to the low temperature in the cold storage, the temperature distribution within the elevator shaft is uneven as the shaft height varies. Condensation occurs on the surface of the elevator car during use, which eventually freezes over time, affecting the smoothness of elevator operation. This situation warrants improvement. Summary of the Invention

[0004] In order to reduce the generation of condensation on the surface of the elevator car and thus improve the safety of the elevator car during operation, this application provides a cold storage elevator car with anti-condensation function.

[0005] This application provides a cold storage elevator car with anti-condensation technology, which adopts the following technical solution: A cold storage elevator car designed to prevent condensation includes a car body and further includes... A protective shell, which is fixed to the outer wall of the compartment. A rough layer is provided on both the outer and inner walls of the compartment; A reinforcing member is provided on the body, and the roughening layer is fixed to the outer wall of the reinforcing member.

[0006] By adopting the above technical solution, the design of the compartment facilitates the transportation of products in the cold storage. The rough layer is fixed to the surface of the compartment by spraying. After the rough layer is fixed, the reinforcing member is located inside the rough layer. The setting of the reinforcing member improves the stability of the rough layer and reduces the possibility of the rough layer falling off. The traction cable used for the car to run passes through the protective shell. The setting of the protective shell plays a protective role, facilitates the installation of the compartment, and reduces the possibility of the rough layer rubbing against external objects during the operation of the compartment. The setting of the rough layer makes the surface of the compartment rougher, reducing the possibility of condensation droplets forming on the outer wall of the compartment and reducing the probability of ice forming on the outer wall of the compartment, thereby improving the stability of the car during operation.

[0007] Optionally, the reinforcing member includes a plurality of positioning posts fixed to the outer wall of the compartment and steel wire ropes wound between the positioning posts. The positioning posts and the steel wire ropes form a mesh-like structure, and the rough layer is fixed to the positioning posts and the steel wire ropes.

[0008] By adopting the above technical solution, during the production of the car, workers weld and fix multiple positioning posts to the surface of the car body, and then wrap steel wire ropes between adjacent positioning posts. The winding of the steel wire ropes makes the positioning posts and steel wire ropes form a mesh structure, which better supports the rough layer and reduces the possibility of the rough layer falling off.

[0009] Optionally, a drive frame is slidably connected to the inner wall of the compartment, and several support wheels rotate on the drive frame. The reinforcing member includes several first traction ropes and several second traction ropes wound around the support wheels. The first traction ropes and second traction ropes are arranged in a crisscross pattern. Both ends of the first traction ropes are fixedly connected to the compartment. Several sliding blocks are slidably connected to the side wall of the compartment. A chain is connected between adjacent sliding blocks. The sliding blocks at the edges are fixedly connected to the drive frame. One end of the second traction rope is fixedly connected to one of the sliding blocks, and the other end is fixedly connected to the opposite sliding block. Rollers rotate on the inner wall of the compartment. The first traction ropes pass around the rollers. Chains are connected between adjacent sliding blocks. The chains at the edges are fixed to the side wall of the drive frame and the side wall of the compartment, respectively. A drive assembly for driving the drive frame to slide is provided on the compartment.

[0010] By adopting the above technical solution, during the production of the car, the first traction rope is passed around the support wheel and roller, and the second traction rope is fixed between two opposing sliding blocks. The drive assembly is activated, which drives the drive frame to slide. The drive frame drives the support wheel and roller to move. Driven by the first traction rope, the support wheel and roller roll. During the sliding of the drive frame, the sliding blocks slide. The sliding blocks slide, so that both the first and second traction ropes are taut on the surface of the car body. At this time, a rough layer is sprayed onto the surface of the car body. The rough layer buries both the first and second traction ropes within it. With the support of the support wheel and roller, the first traction rope becomes more compact. The stability of the rough layer is enhanced by the support of the first and second traction ropes, reducing the possibility of the rough layer falling off.

[0011] Optionally, the drive assembly includes a lead screw that rotates on the inner wall of the chamber and a threaded sleeve that is threaded onto the outer wall of the lead screw. The drive frame is fixedly connected to the outer wall of the threaded sleeve, and a rotating sleeve is fixed to the end of the lead screw. The inner wall of the rotating sleeve is non-circular.

[0012] By adopting the above technical solution, during the assembly of the compartment, the workers insert a wrench or a rotating handle onto the rotating sleeve. As the rotating sleeve rotates, it drives the lead screw to rotate. The threaded sleeve slides on the outer wall of the lead screw, and the threaded sleeve pulls the frame to slide, thereby arranging the first traction rope and the second traction rope on the inner wall of the compartment.

[0013] Optionally, a plurality of third traction ropes are provided on the outer wall of the compartment, and a plurality of through holes are provided on the side wall of the protective shell. Both ends of the third traction ropes are fixedly connected to the outer wall of the compartment, and the third traction ropes pass through the through holes.

[0014] By adopting the above technical solution, the third traction rope is fixed by the protruding part of the protective shell, making the fixation of the third traction rope more stable. The opening of the through hole facilitates the insertion of the third traction rope. The workers spray the raw material of the rough layer onto the outer wall of the compartment to form a rough layer on the outer wall of the compartment. With the support of the third traction rope, the fixation of the rough layer is more stable, reducing the possibility of the rough layer falling off.

[0015] Optionally, several columns are fixed on the outer wall of the container, the third traction rope is wound around the columns, and a fourth traction rope is wound and fixed between the columns, with the third traction rope and the fourth traction rope arranged at an angle.

[0016] By adopting the above technical solution, the column setting facilitates the fixing of the fourth traction rope. With the support of the column, the fourth traction rope and the third traction rope are woven together. With the support of the third traction rope and the fourth traction rope, the fixing of the rough layer is more stable, thus making the rough layer better protect the outer wall of the compartment.

[0017] Optionally, the roller has several guide grooves on its side wall, and the first traction rope is located in the corresponding guide groove. The distances between the several first traction ropes and the outer wall of the compartment are not equal.

[0018] By adopting the above technical solution, the opening of the guide groove facilitates the separate winding of the first traction rope. Under the restriction of the guide groove, the distance between the first traction rope and the outer wall of the compartment is not equal, which supports the rough layer at different thicknesses, thereby making the support of the rough layer more stable.

[0019] Optionally, both the positioning post and the end of the post body are fixed with blocking blocks.

[0020] By adopting the above technical solution, the setting of the limiting plate blocks the steel wire rope and the fourth traction rope, reducing the possibility of the steel wire rope detaching from the positioning column and reducing the possibility of the fourth traction rope detaching from the column.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. During the manufacturing process of the elevator car, the workers pre-install reinforcing components on the inner and outer walls of the car, and then fix a rough layer on the inner and outer walls of the car so that the reinforcing components are located inside the rough layer. The rough layer enhances the roughness of the outer wall of the elevator car, thereby reducing the possibility of condensation and ice formation on the outer wall of the elevator car due to the temperature difference between the cold storage and the inner wall of the shaft, and reducing the impact on the movement of the elevator car.

[0022] 2. During the production of the single-unit car, one end of the first traction rope is pre-fixed to the outer wall of the car body. Then, the first traction rope is passed around the support wheel, so that the free ends of several first traction ropes are gathered together. The free ends of the first traction ropes are then fixed to the outer wall of the car body. Then, the drive assembly is activated, which drives the drive frame to slide. During the movement of the drive frame, the sliding block slides, stretching the first traction rope and the second traction rope onto the side wall of the car body. Then, a fixing rough layer is sprayed onto the outer wall of the car body, making the stretching of the first traction rope and the second traction rope more convenient, thus saving workers a lot of time.

[0023] 3. Since the protective shell is located on the outer wall of the compartment, the workers thread the third traction rope through the through hole, making reasonable use of the support of the protective shell on the third traction rope, reducing the need to fix several positioning posts on the outer wall of the compartment, thereby saving the use of parts and labor costs.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses an anti-condensation elevator car for cold storage elevators.

[0031] Example 1, Reference Figure 1 and Figure 2 A cold storage elevator car with anti-condensation function includes a car body 1 and a protective shell 2 integrally fixed to the outer wall of the car body 1. In this application, both ends of the protective shell 2 are open. The protective shell 2 is set along the height direction of the car body 1. The support frame on the elevator car for installing the car body 1 passes through the inner cavity of the protective shell 2 and is fixed to the outer wall of the car body 1. The setting of the protective shell 2 facilitates the fixing of the support frame on the outer wall of the car body 1 and plays a role in protecting the structure on the outer wall of the car body 1, reducing the impact caused during the sliding of the elevator car.

[0032] Reference Figure 1 A rough layer 3 is fixed on the outer wall of the compartment 1 by spraying. In this application, the rough layer 3 is preferably made of polyurethane foam. The optimal thickness of the rough layer 3 is 38mm-42mm. The rough layer 3 protects the outer wall of the compartment 1 on the one hand, and increases the roughness of the outer wall of the compartment 1 on the other hand, reducing the possibility of condensation on the outer wall of the compartment 1 due to the large temperature difference between the cold storage and the inner wall of the shaft. This reduces the possibility of ice formation on the outer wall of the compartment 1 affecting the movement of the elevator car.

[0033] Reference Figure 2 and Figure 3 The reinforcing component 4 includes several positioning posts 41 welded and fixed to the outer wall of the compartment 1, and a steel wire rope 42 wound between two positioning posts 41. A blocking block 19 is welded and fixed to the end of each positioning post 41. The blocking block 19 is preferably perpendicular to the positioning post 41. The blocking block 19 limits the movement of the steel wire rope 42, reducing the possibility of the steel wire rope 42 detaching from the positioning post 41. After the workers have pre-installed the positioning posts 41 and the steel wire rope 42, they spray a roughening layer 3 onto the outer wall of the compartment 1. The positioning posts 41, steel wire rope 42, and blocking block 19 are all wrapped in the roughening layer 3. The reinforcing component 4 acts to pull the roughening layer 3, reducing the possibility of the roughening layer 3 falling off.

[0034] According to Embodiment 1 of this application, the implementation principle of an anti-condensation elevator car for cold storage is as follows: During the production of the elevator car, workers pre-weld and fix several positioning columns 41 on the outer and inner walls of the car body 1. Each positioning column 41 is welded and fixed with a blocking block 19. Then, steel wire ropes 42 are wound around the positioning columns 41, so that the inner and outer layers of the car body 1 are in the form of a wire mesh. A roughening layer 3 is sprayed and fixed onto the outer wall, inner wall and top wall of the car body 1, making the outer wall of the car body 1 rougher, thereby reducing the formation of condensation droplets on the outer wall of the car body 1 due to temperature difference, and preventing the possibility of ice formation affecting the slippage of the car body 1 and the electronic components on the car body 1.

[0035] Example 2, Example 2 differs from Example 1 in that: (Refer to...) Figure 1 and Figure 4 The inner wall of the compartment 1 is provided with a sliding groove, and a drive frame 5 is slidably connected to the inner wall of the compartment 1. The drive frame 5 is slidably connected to the inner wall of the sliding groove. In this application, three drive frames 5 are preferably provided. The three drive frames 5 are respectively provided on the inner side wall and the top wall of the compartment 1. Several support wheels 6 are rotatably connected to the side wall of each drive frame 5 through a rotating shaft. Six support wheels 6 are preferably provided on one drive frame 5. Rollers 11 are rotatably connected to the inner wall of the compartment 1 through a rotating shaft. There are three rollers 11. The reinforcing member 4 includes several first traction ropes 43 that are fixed to the inner wall of the compartment 1 by riveting. One end of the first traction rope 43 is riveted to the inner wall of the compartment 1, and the other end passes around the support wheel 6 and the roller 11 and is riveted to the inner wall of the compartment 1. A drive assembly 12 for driving the drive frame 5 to slide is provided on the inner wall of the compartment 1. The drive assembly 12 drives the drive frame 5 to slide, and the first traction ropes 43 are arranged on the inner wall of the compartment 1.

[0036] Reference Figure 4 Several sliding blocks 9 are slidably connected to the inner wall of the compartment 1. A chain 10 is connected between two adjacent sliding blocks 9 along the length direction of the compartment 1. The end of the chain 10 near the edge of the drive frame 5 that is away from the sliding block 9 is fixedly connected to the side wall of the drive frame 5 by screws. The end of the chain 10 away from the edge of the drive frame 5 that is away from the sliding block 9 is fixedly connected to the inner wall of the compartment 1 by screws. During the sliding process of the drive frame 5, the chain 10 is moved, thereby causing the sliding blocks 9 to slide. The sliding blocks 9 are evenly arranged along the length direction of the inner wall of the compartment 1.

[0037] Reference Figure 4The reinforcing member 4 also includes several second traction ropes 44. One end of the second traction rope 44 is riveted to the side wall of one of the sliding blocks 9, and the other end is riveted to the side wall of the opposite sliding block 9. The first traction rope 43 and the second traction rope 44 are arranged in a cross pattern. After the sliding blocks 9 are pulled and distributed on the inner wall of the compartment 1, the first traction rope 43 and the second traction rope 44 are both arranged on the inner wall of the compartment 1, which makes it easier to arrange the first traction rope 43 and the second traction rope 44 on the inner wall of the compartment 1.

[0038] Reference Figure 4 The distances between the support wheels 6 on the same drive frame 5 and the side wall of the drive frame 5 are not equal. The side wall of the roller 11 is provided with a number of guide grooves 18 at even intervals. The guide grooves 18 are arranged along the axial direction of the roller 11. The first traction rope 43 is set in a one-to-one correspondence with the guide groove 18. The first traction rope 43 is wound in the guide groove 18. Under the support of the support wheels 6 and the roller 11, the distances between the first traction ropes 43 and the outer wall of the box body 1 are not equal, so that the traction limit of the rough layer 3 is more stable.

[0039] Reference Figure 4 The inner wall of the compartment 1 is provided with a drive assembly 12 for driving the drive frame 5 to slide. The drive assembly 12 includes a lead screw 121 that rotates on the inner wall of the compartment 1 and a threaded sleeve 122 that is threaded to the outer wall of the lead screw 121. The threaded sleeve 122 is located between two drive frames 5. Two adjacent drive frames 5 are welded and fixed to the outer wall of the threaded sleeve 122. A rotating sleeve 13 is fixed to the end of the lead screw 121. The inner wall of the rotating sleeve 13 is hexagonal. The operator inserts a rotating handle into the rotating sleeve 13. The rotating handle is Z-shaped. Rotating the rotating handle causes the lead screw 121 to rotate, thereby driving the drive frame 5 to slide.

[0040] Reference Figure 4 The protective shell 2 has several through holes 15 on its side walls. The through holes 15 are arranged along the length of the protective shell 2. Several third traction ropes 14 are fixed to the outer wall of the body 1 by rivets. The third traction ropes 14 pass through the through holes 15. The protective shell 2 supports the third traction ropes 14, making the fixation of the third traction ropes 14 more stable.

[0041] Reference Figure 4 Several columns 16 are welded and fixed on the outer wall of the compartment 1. A fourth traction rope 17 is attached between every two columns 16. The third traction rope 14 and the fourth traction rope 17 are fixed to the outer wall of the compartment 1 in a cross manner. A rough layer 3 is sprayed onto the outer wall of the compartment 1. The third traction rope 14 and the fourth traction rope 17 are both buried in the rough layer 3 to pull and fix the rough layer 3, thereby making the fixation of the rough layer 3 more stable.

[0042] Reference Figure 4 The ends of the column 16 are all welded with fixed blocking blocks 19. The blocking blocks 19 are located in the rough layer 3. The setting of the blocking blocks 19 increases the contact area between the column 16 and the rough layer, and also limits the fourth traction rope 17, reducing the possibility of the fourth traction rope 17 detaching from the column 16, thereby improving the stability of the rough layer 3.

[0043] According to Embodiment 2 of this application, the implementation principle of an anti-condensation elevator car for a cold storage elevator is as follows: The operator fixes one end of the first traction rope 43 inside the car body 1 near the drive frame 5, then winds the first traction rope 43 around the support wheel 6 and roller 11, and fixes the other end of the first traction rope 43 to the inner wall of the car body 1. A rotating handle matching the inner wall of the rotating sleeve 13 is inserted into the rotating sleeve 13. The rotating handle drives the rotating sleeve 13 to rotate, and the rotating sleeve 13 drives the lead screw 121 to rotate. The threaded sleeve 122 slides on the outer wall of the lead screw 121, thereby driving the drive frame 5 to slide. With the support of the support wheel 6 and roller 11, the first traction rope 43 and the second traction rope 44 are arranged on the inner wall of the car body 1. Then, a rough layer 3 is sprayed onto the inner and outer walls of the car body 1. The rough layer 3 increases the roughness of the outer wall of the car body 1, thereby reducing the possibility of condensation droplets forming on the outer wall of the car body 1.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
