Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator car technology, and in particular to a reinforcing component for an elevator car panel. Background Technology
[0002] The car frame, as a load-bearing frame, is a rigid structure welded together from components such as the upper beam, columns, base, and bottom beam. The main body of the car consists of four metal reinforcing plates with alternating concave and convex bends along its width and four flat stainless steel plates. During assembly, the stainless steel plates are first welded one by one onto the metal reinforcing plates to form the car panels. Then, the four car panels are erected, and one of the width edges of the car panels is welded to the corresponding boundary on the base. The four car panels are then welded and fixed sequentially along the circumference of the top of the base. Next, adjacent car panels are welded and fixed together to form a hollow rectangular car. Finally, the top cover is welded and fixed to the top of the car to complete the roof assembly, thus completing the main body assembly of the car. One of the car panels needs to have a doorway pre-cut for entry and exit.
[0003] Because the stainless steel plate and the metal reinforcing plate are only fixed by edge welding, it is difficult to effectively fix other contact points between them. This results in relatively poor structural strength after assembly. In the event of a brake device failure and fall, the connection between the metal reinforcing plate and the stainless steel plate is prone to tearing due to severe impact. This can cause serious deformation or detachment of the car due to its weak structural strength, which can easily cause secondary injuries to passengers inside the car. Therefore, its protection effect on passengers is relatively poor. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a reinforcing component for elevator car panels to solve the problem of severe deformation or detachment of the car due to poor structural strength and connection firmness during violent impact.
[0005] To achieve the above objectives, this utility model provides a reinforcing assembly for an elevator car panel, comprising an inner groove and an outer groove formed by alternating inward and outward folded metal reinforcing plates. The reinforcing assembly further includes:
[0006] Several horizontal support rods are arranged vertically side by side in the inner groove.
[0007] The connector fixed to the stainless steel plate has a limiting groove at the bottom of its fastening block. The horizontal support rod is fastened into the limiting groove to enhance the lateral connection strength and vertical support strength between the stainless steel plate and the metal reinforcing plate.
[0008] Several lower limit blocks are circumferentially located at the top of the base, and are inserted and welded to the bottom of the outer groove to strengthen the connection between the base and the metal reinforcing plate.
[0009] Several upper limit blocks are circumferentially located at the bottom of the top cover, and are inserted and welded to the top of the outer groove to strengthen the connection between the top cover and the metal reinforcing plate.
[0010] Preferably, the reinforcing component further includes:
[0011] Several reinforcing ribs are fixed in parallel to the top of the cover to enhance the horizontal structural strength of the cover.
[0012] The plug-in blocks are fixed at the four corners of the bottom of the top cover and are inserted into the included groove formed between two adjacent metal reinforcing plates.
[0013] The lower convex plate, fixed to the bottom of the top cover, is inserted and welded to the top of the car interior, and works with the upper limit block to strengthen the connection and structural strength between the top cover and the car.
[0014] Preferably, the length of the reinforcing rib is equal to the side length of the top cover, and the reinforcing rib is a hollow square tube.
[0015] Preferably, the top of the reinforcing rib is fixedly disposed at the bottom of the upper beam, and the reinforcing rib and the upper limit block are staggered in the horizontal direction.
[0016] Preferably, the shape and size of the plug block match the shape and size of the cross-section within the included groove, and the plug block is located between the metal reinforcing plate and the stainless steel plate.
[0017] Preferably, the upper limit block has the same structure as the lower limit block, and the interior of the upper limit block is hollow.
[0018] Preferably, the upper limit block and the lower convex plate are clamped at the top of both sides of the stainless steel plate, and the corners of the plug block and the lower convex plate are clamped at the connection point of the tops of two adjacent stainless steel plates.
[0019] Preferably, the horizontal support rod is fixed laterally inside the inner groove, and the horizontal support rod is located between the metal reinforcing plate and the stainless steel plate.
[0020] The beneficial effects of this utility model are:
[0021] This invention utilizes a series of connectors on a stainless steel plate that correspond one-to-one with a series of horizontal support rods in the inner grooves of a metal reinforcing plate. The connectors are inserted horizontally into the inner grooves and then moved vertically downwards to engage with the horizontal support rods. The stainless steel plate and the metal reinforcing plate are then welded together, allowing the horizontal support rods to vertically support the connectors and the stainless steel plate. This enhances the vertical connection strength and structural strength between the stainless steel plate and the metal reinforcing plate, improving their resistance to vertical impacts and reducing the deformation of the car under severe impacts, thus protecting the safety of passengers inside the car. Furthermore, limiting blocks located on the boundaries of the base and top cover are inserted into the corresponding outer grooves at the bottom and top of the metal reinforcing plate and then fixed by welding, improving the lateral structural strength of the top and bottom of the car and increasing the welded fixing points between the car and the base and top cover, thereby enhancing the connection stability of the car.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0033] like Figures 1 to 6 As shown, a reinforcing assembly for an elevator car panel includes an inner groove 2 and an outer groove 1 formed by alternating inward and outward folded metal reinforcing plates. The reinforcing assembly further includes:
[0034] Several horizontal support rods 3 are arranged vertically side by side in the inner groove 2.
[0035] The connector 4, fixed to the stainless steel plate, has a limiting groove 42 at the bottom of its fastening block 41. The horizontal support rod 3 is fastened in the limiting groove 42, which increases the connection and support points between the stainless steel plate and the metal reinforcing plate. This strengthens the lateral connection strength and vertical support strength between the stainless steel plate and the metal reinforcing plate, improves the car's resistance to impact during a fall, reduces the degree of deformation of the car, and prevents the car from injuring passengers inside due to excessive deformation, thus improving the protection effect for passengers.
[0036] Several lower limit blocks 5 are circumferentially located on the top of the base and are inserted and welded to the bottom of the outer groove 1. They are used to strengthen the connection between the base and the metal reinforcing plate, prevent the metal reinforcing plate from undergoing lateral displacement under the influence of impact force, and avoid the dangerous situation of the car separating from the base, thereby improving the safety of the car.
[0037] Several upper limit blocks 9 are circumferentially located at the bottom of the top cover, inserted and welded to the top of the outer groove 1, increasing the fixed connection between the top cover and the top of the car, and strengthening the connection between the top cover and the metal reinforcing plate. This prevents the top cover from detaching from the bottom and top of the car or immersing in the car and injuring passengers under the impact of the car falling, thus further ensuring the safety of passengers in the car.
[0038] like Figure 1 , Figure 5 and Figure 6 As shown, the reinforcement components also include:
[0039] Several reinforcing ribs 6 are fixed in parallel to the top of the cover to enhance the horizontal structural strength of the cover.
[0040] The plug-in blocks 7 are fixed at the four corners of the bottom of the top cover. The plug-in blocks 7 are inserted into the included groove formed by the enclosing of two adjacent metal reinforcing plates. This design improves the structural strength and connection strength of the top cover in the horizontal direction, and prevents the top cover from undergoing severe collapse deformation under violent impact and falling into the car.
[0041] The lower convex plate 8, fixed to the bottom of the top cover, is inserted and welded to the top of the car interior. Together with the upper limit block 9, it strengthens the connection and structural strength between the top cover and the car, preventing the car from falling and causing the top cover to collapse and deform severely, detach from the top of the car, and fall into the car to injure passengers.
[0042] like Figure 1 , Figure 5 and Figure 6 As shown, the length of the reinforcing rib 6 is equal to the side length of the top cover, and the reinforcing rib 6 is a hollow square tube.
[0043] The top of the reinforcing rib 6 is fixed to the bottom of the upper beam, and the reinforcing rib 6 and the upper limit block 9 are staggered in the horizontal direction. This design can improve the structural strength of the car and the connection strength between the components, while also improving the overall lightweight design. Since the impact force is proportional to the weight, the lightweight design can reduce the degree of deformation of the car during an impact.
[0044] like Figure 2 and Figure 6 As shown, the shape and size of the plug block 7 match the shape and size of the cross section inside the angled groove, and the plug block 7 is located between the metal reinforcing plate and the stainless steel plate. This design further improves the horizontal connection strength between the top cover and the top of the car, further preventing the top cover from undergoing severe collapse deformation during a violent impact and falling into the car to injure passengers, thus improving the safety of the top cover.
[0045] like Figure 1 , Figure 5 and Figure 6As shown, the structure of the upper limit block 9 is the same as that of the lower limit block 5, and the interior of the upper limit block 9 is hollow. This design strengthens the structural strength and connection strength of the top cover while improving the lightweight design of the top cover and reducing the impact of weight on the deformation of the top cover.
[0046] like Figures 1 to 6 As shown, the upper limit block 9 and the lower convex plate 8 are clamped on the top of both sides of the stainless steel plate, and the corners of the plug block 7 and the lower convex plate 8 are clamped at the connection point of the top of two adjacent stainless steel plates.
[0047] The horizontal support rod 3 is fixed horizontally inside the inner groove 2, and the horizontal support rod 3 is located between the metal reinforcing plate and the stainless steel plate. This design reduces the impact on the structural strength of the stainless steel plate when it is subjected to severe impact due to the excessive buffer space.
[0048] Working principle: During assembly, a metal reinforcing plate is first welded and fixed to the top edge of the base. During this process, the lower limit block 5 is inserted and welded into the corresponding outer groove 1. Then, the side of the stainless steel plate with the fastening block 41 faces the metal reinforcing plate, and the fastening block 41 is inserted horizontally into the top of the corresponding horizontal support rod 3. Then, the stainless steel plate is lowered so that the horizontal support rod 3 is fastened into the limiting groove 42 on the fastening block 41, completing the initial installation between the stainless steel plate and the metal reinforcing plate. This operation is repeated to install the remaining metal reinforcing plates and stainless steel plates into place, and the connection boundary between two adjacent metal reinforcing plates is welded and fixed. At the same time, the adjacent boundary between two adjacent stainless steel plates is welded and fixed. In this way, several horizontal support rods 3 vertically support several connections. Component 4 increases the vertical structural strength between the metal reinforcing plate and the stainless steel plate, preventing severe collapse deformation and detachment from the base when the car falls, thus improving the car's protection for passengers and preventing injury to passengers due to severe deformation. The top cover is placed on top of the car, and the top of the stainless steel plate is tightly inserted into the upper limit block 9 and the lower convex plate 8. The joints of two adjacent stainless steel plates are tightly inserted between the corners of the insertion block 7 and the lower convex plate 8. The boundaries of the top cover and the upper limit block 9 are welded and fixed to the car, improving the horizontal structural strength and connection strength of the top cover, preventing severe collapse deformation and falling into the car, and injuring passengers inside the car, thus improving the protection for passengers.
