Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments in this utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this utility model.
[0033] As recorded in the background art, in the design of traditional freight elevators, the inner wall of the car is often directly exposed during the process of cargo handling, lacking necessary protective measures. Due to the different shapes, sizes, and weights of the goods, collisions or frictions are inevitable during the handling process. These impacts will not only cause scratches, dents, or even cracks on the inner wall of the car, but may also damage the overall structure of the elevator, affecting the safety and stability of the elevator.
[0034] To solve this technical problem, this utility model provides an anti-collision device for a freight elevator car.
[0035] Specifically, please refer to Figures 1 - 5 , the anti-collision device for the freight elevator car specifically includes:
[0036] A support structure 1 and a protection plate 2 located on one side of the support structure 1. A through opening 201 is provided on the protection plate 2. The support structure 1 includes a support base 101. A chamber 6 is provided in the support base 101. A connecting shaft 5 is inserted and connected in the chamber 6. One end of the connecting shaft 5 passes through the chamber 6 and is fixedly connected to a limiting plate 104.
[0037] The anti-collision device for the cargo elevator car provided by the utility model. Through the protective plate 2 provided in this application, the inner wall of the car can be protected, effectively preventing the damage of the car caused by the impact of goods, reducing the maintenance cost of the elevator, and extending the service life of the elevator. The protective plate 2 and the support structure 1 adopt a quick-detachable design, which is convenient for maintenance or replacement when needed, improving the flexibility and maintainability of the device.
[0038] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings.
[0039] It should be noted that, without conflict, the embodiments in the utility model and the features and technical solutions in the embodiments can be combined with each other.
[0040] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0041] Embodiment 1. Please refer to Figures 1 - 5 , an anti-collision device for a cargo elevator car, including a support structure 1 and a protective plate 2 located on one side of the support structure 1. A through hole 201 is provided on the protective plate 2. The support structure 1 includes a support base 101. A cavity 6 is provided in the support base 101. A connecting shaft 5 is inserted and connected in the cavity 6. One end of the connecting shaft 5 passes through the cavity 6 and is fixedly connected with a limiting plate 104. Through the protective plate 2 provided in this application, the inner wall of the car can be protected, effectively preventing the damage of the car caused by the impact of goods, reducing the maintenance cost of the elevator, and extending the service life of the elevator. The protective plate 2 and the support structure 1 adopt a quick-detachable design, which is convenient for maintenance or replacement when needed, improving the flexibility and maintainability of the device.
[0042] Further, as Figure 5 shown, a spring 4 is sleeved on the outer surface of the connecting shaft 5. The spring 4 is located in the cavity 6. The spring 4 can pull the limiting plate 104 through the connecting shaft 5 so that the limiting plate 104 can clamp the protective plate 2.
[0043] Further, the cross-section of the connecting shaft 5 is circularly arranged, so that the limiting plate 104 can rotate.
[0044] Embodiment 2. The anti-collision device for the cargo elevator car provided in Embodiment 1 is further optimized. Specifically, as Figure 1 and Figure 3As shown in the figure, two limiting grooves 202 are formed in the protective plate 2. Both of the two limiting grooves 202 are perpendicular to the through port 201, and the limiting plate 104 is inserted between the two limiting grooves 202. The limiting of the limiting plate 104 by the limiting grooves 202 can prevent the limiting plate 104 from rotating by itself. Pull the limiting plate 104 to separate it from the limiting grooves 202, and then rotate the limiting plate 104 so that the limiting plate 104 is parallel to the through port 201. At this time, the limiting of the protective plate 2 by the limiting plate 104 can be released. Pull the protective plate 2 so that the limiting plate 104 passes through the through port 201, and then the protective plate 2 can be removed. When installing, pass the limiting plate 104 through the through port 201 and then rotate it by ninety degrees.
[0045] Further, as Figure 2 and Figure 3 shown, both ends of the support structure 1 are fixedly connected with first support rods 102. Two second support rods 105 are arranged between the two first support rods 102. Installation holes are formed in the first support rods 102. The first support rods 102 can be connected to the inner wall of the car by gluing, or can be connected to the inner wall of the car by bolts passing through the installation holes.
[0046] Further, limiting members are arranged between both of the two second support rods 105 and the protective plate 2. The limiting members are used for limiting the protective plate 2 and the second support rods 105 to improve the stability of the protective plate 2.
[0047] Further, as Figure 1 and Figure 3 shown, the limiting member includes a slot 3 formed in the second support rod 105. A limiting rod 203 is inserted inside the slot 3. The end of the limiting rod 203 is fixedly connected with the protective plate 2. The inner diameter of the slot 3 is adapted to the diameter of the limiting rod 203. After the slot 3 is inserted into the inside of the limiting rod 203, the stability of the connection between the protective plate 2 and the second support rod 105 can be improved by relying on the friction force between the slot 3 and the limiting rod 203.
[0048] Further, as Figure 2 and Figure 3 shown, stoppers 106 are fixedly connected to both ends of the support base 101. The stoppers 106 are in contact with the back surface of the protective plate 2. The stoppers 106 can play an auxiliary supporting role for the protective plate 2.
[0049] Embodiment 3 further optimizes the anti-collision device for the freight elevator car provided in Embodiment 1 or 2. Specifically, the second support rod 105 is fixedly connected to the first support rod 102, and the fixed connection between the second support rod 105 and the first support rod 102 can be realized by welding.
[0050] Embodiment 4 further optimizes the anti-collision device for the freight elevator car provided in Embodiment 1 or 2. Specifically, as Figures 1 - 3As shown, a U-shaped plate 103 is fixedly connected to the first support rod 102. The second support rod 105 is inserted into the inner wall of the U-shaped plate 103, and a bolt is provided between the second support rod 105 and the U-shaped plate 103. Such a setting can facilitate the rotation of the second support rod 105 with a corresponding length according to the situation of the car.
