Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator technology, and in particular to an elevator car top fixing bracket and an elevator car top fixing bracket system. Background Technology
[0002] In existing elevator structures, the car is typically secured using a double connection design at the bottom and top to ensure stability and safety during operation. The bottom of the car is usually firmly fixed to the car frame using bolts or similar rigid connectors, while the top is also connected to the car frame to maintain overall structural balance. However, in most ordinary elevators, to simplify design and reduce costs, a rigid connection method is often used, where the top of the car is directly fixed to the car frame using high-strength bolts. While this connection method is simple in structure and easy to install, the lack of vibration damping mechanisms means that vibrations generated by the car frame during operation are directly transmitted to the inside of the car, leading to significant vibration and noise problems. This vibration and noise are particularly pronounced during elevator start-up, braking, or when passing through floor joints, severely impacting passenger comfort and potentially causing anxiety.
[0003] To enhance the passenger experience, some high-end elevators employ more advanced flexible connection methods. This design typically achieves vibration isolation by installing elastic elements (such as corner rubber limiters) between the top of the car and the car frame. These corner rubber limiters possess elasticity and damping characteristics, absorbing and buffering the vibration energy transmitted by the car frame, thus significantly reducing noise levels inside the car. However, this corner rubber limiting method has some significant limitations in practical applications. First, adjusting the gap between the corner rubber and the car frame columns is very difficult, requiring precise control of the gap size during installation; otherwise, the connection may be too tight (affecting vibration damping) or too loose (reducing structural stability). Second, as a polymer material, corner rubber is prone to aging, hardening, and even cracking when operating under dynamic loads and varying temperature and humidity conditions over long periods, leading to a gradual decline in its vibration damping performance or even complete failure. Once the corner rubber fails, it not only fails to provide vibration damping but may also cause safety hazards due to loose connections.
[0004] Therefore, there is an urgent need to design an elevator car top fixing bracket and an elevator car top fixing bracket system to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide an elevator car top fixing bracket and elevator car top fixing bracket system that is easy to install and debug, not easy to fail, and can reduce the noise between the car and the car frame column.
[0006] To solve the above-mentioned technical problems, this utility model provides an elevator car top fixing frame, including a base plate frame, two curved plates symmetrically arranged at both ends of the base plate frame, two first anti-collision members symmetrically arranged at both ends of the base plate frame, and two second anti-collision members symmetrically arranged at both ends of the base plate frame. The curved plates, first anti-collision members, and second anti-collision members correspond one-to-one. The curved plates are fixed to the base plate frame, and each curved plate includes a first stiffener and a second stiffener. The first stiffener and the second stiffener are perpendicular to each other to form an L-shaped structure. The first stiffener is connected to the corresponding first anti-collision member, and the second... The stiffening plate is connected to the corresponding second anti-collision member; both the first and second anti-collision members include a nut, a bolt, and an anti-collision layer covering the head of the bolt; the nut of the first anti-collision member is fixed to the corresponding first stiffening plate, and the bolt of the first anti-collision member is locked to the corresponding first stiffening plate by the corresponding nut, so that the corresponding anti-collision layer abuts against the external car frame column; the nut of the second anti-collision member is fixed to the corresponding second stiffening plate, and the bolt of the second anti-collision member is locked to the corresponding second stiffening plate by the corresponding nut, so that the corresponding anti-collision layer abuts against the external car frame column.
[0007] As an improvement to the above solution, it also includes several reinforcing plates, which are connected to the bending plate and the base plate frame.
[0008] As an improvement to the above solution, the reinforcing plate is a right-angled triangular prism structure, with one right-angled side of the reinforcing plate connected to the bent plate, and the other right-angled side of the reinforcing plate connected to the base plate frame.
[0009] As an improvement to the above solution, the bolt has a boss at its end.
[0010] As an improvement to the above solution, the anti-collision layer is a polyurethane anti-collision layer.
[0011] As an improvement to the above solution, the nut and anti-collision layer of the first anti-collision member are respectively disposed on both sides of the corresponding first rib, and the screw of the first anti-collision member passes through the first rib from one side and is locked with the corresponding nut; the nut and anti-collision layer of the second anti-collision member are respectively disposed on both sides of the corresponding second rib, and the screw of the second anti-collision member passes through the first rib from one side and is locked with the corresponding nut.
[0012] As an improvement to the above solution, the first anti-collision component and the corresponding second anti-collision component are perpendicular to each other.
[0013] Accordingly, this utility model also provides an elevator car top fixing frame system, including at least two elevator car top fixing frames, a car, and four car frame columns. The car frame columns, the first anti-collision member, and the second anti-collision member correspond one-to-one, and the anti-collision layer of the first anti-collision member and the second anti-collision member abuts against the corresponding car frame column.
[0014] As an improvement to the above solution, a top plate end cap is provided above the car, and the top plate end cap is connected to the bottom plate frame.
[0015] The beneficial effects of implementing this utility model are as follows:
[0016] In this invention, by setting a first and a second anti-collision member and abutting them against the car frame column, a flexible connection is achieved between the car and the car frame column. This reduces the noise generated by collisions between the car and the car frame column during elevator operation and reduces the likelihood of anti-collision member failure. Furthermore, since the first and second anti-collision members penetrate the first and second stiffening plates respectively, and the first and second stiffening plates are perpendicular to each other to form an L-shaped structure, maintenance personnel can adjust the tightness of the elevator car top fixing frame from two different directions, making elevator debugging easier.

[0021] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.
[0022] See Figure 1 , Figure 2 and Figure 3 , Figure 1 , Figure 2 and Figure 3The specific structure of the elevator car top fixing frame of this utility model is shown, including a base plate frame 1, two curved plates 2 symmetrically arranged at both ends of the base plate frame 1, two first anti-collision members 3 symmetrically arranged at both ends of the base plate frame 1, and two second anti-collision members 4 symmetrically arranged at both ends of the base plate frame 1. The curved plates 2, the first anti-collision members 3, and the second anti-collision members 4 correspond one-to-one. The curved plates 2 are fixed on the base plate frame 1. The curved plates 2 include a first stiffener 21 and a second stiffener 22. The first stiffener 21 and the second stiffener 22 are perpendicular to each other to form an L-shaped structure. The first stiffener 21 is connected to the corresponding first anti-collision member 3, and the second stiffener 22 is connected to the corresponding second anti-collision member 4. Both the first anti-collision member 3 and the second anti-collision member 4 include a nut 23, a bolt 24, and an anti-collision layer 25 covering the head of the bolt 24. The nut 23 of the first anti-collision member 3 is fixed to the corresponding first stiffener 21, and the bolt 24 of the first anti-collision member 3 is locked to the corresponding first stiffener 21 by the corresponding nut 23, so that the corresponding anti-collision layer 25 abuts against the external car frame column 5. The nut 23 of the second anti-collision member 4 is fixed to the corresponding second stiffener 22, and the bolt 24 of the second anti-collision member 4 is locked to the corresponding second stiffener 22 by the corresponding nut 23, so that the corresponding anti-collision layer 25 abuts against the external car frame column 5.
[0023] It should be noted that by setting two symmetrical curved plates 2, and setting the first stiffener 21 and the second stiffener 22 of the curved plates 2 into a mutually perpendicular L-shaped structure, and by having two first anti-collision members 3 and two second anti-collision members 4 located at both ends of the base plate frame 1 pass through the corresponding first stiffener 21 and second stiffener 22 respectively, the elevator car top fixing frame achieves structural symmetry. Furthermore, by having the bolts 24 of the first anti-collision member 3 and the second anti-collision member 4 abut against the external car frame column 5, the elevator car top fixing frame can bear force evenly at both ends when the car 7 shakes due to movement, preventing excessive wear of the anti-collision members on one side. By using the structure of nuts 23 and bolts 24, and fixing them to the first stiffener 21 and the second stiffener 22, it is not easy for the base plate frame 1 to loosen with the first anti-collision members 3 and the second anti-collision members 4.
[0024] Specifically, it also includes several reinforcing plates 6, which are connected to the bending plate 2 and the base plate frame 1. By setting the reinforcing plates 6, the stability of the connection between the bending plate 2 and the base plate frame 1 is further enhanced.
[0025] It should be noted that in this embodiment, two reinforcing plates 6 are used, which are used to fix the two symmetrical curved plates 2 to the base plate frame 1 respectively.
[0026] Preferably, the reinforcing plate 6 is a right-angled triangular prism structure, with one right-angled side of the reinforcing plate 6 connected to the curved plate 2, and the other right-angled side of the reinforcing plate 6 connected to the base plate frame 1. Therefore, one side of the reinforcing plate 6 that is attached to the curved plate 2 and one side that is attached to the base plate frame 1 can form a 90° angle, so that the torsional resistance of the reinforcing plate 6 is maximized.
[0027] Preferably, the bolt 24 has a boss at its end. This allows maintenance personnel to use pliers to clamp the end of the bolt 24 to secure the anti-collision component, and then tighten the nut 23 with a wrench.
[0028] It should be noted that the anti-collision layer 25 is a polyurethane anti-collision layer, which can effectively reduce the noise when the car frame column 5 collides with the car 7. It should also be noted that other materials with good cushioning performance can also be used as the anti-collision layer 25 of this elevator car top fixing frame, but are not limited to this.
[0029] Specifically, the nut 23 and anti-collision layer 25 of the first anti-collision component 3 are respectively disposed on both sides of the corresponding first rib 21. The screw 26 of the first anti-collision component 3 passes through the first rib 21 from one side and locks with the corresponding nut 23. The nut 23 and anti-collision layer 25 of the second anti-collision component 4 are respectively disposed on both sides of the corresponding second rib 22. The screw 26 of the second anti-collision component 4 passes through the first rib 21 from one side and locks with the corresponding nut 23. By disposing of the nut 23 and anti-collision layer 25 on both sides of the rib, a stable connection is achieved between the anti-collision component and the rib, preventing loosening. Furthermore, the method of passing the bolt 24 through the rib and then locking it with the nut 23 is easier to align than the corner glue connection method, making it more convenient for maintenance workers to install and repair.
[0030] Preferably, the first anti-collision member 3 and the corresponding second anti-collision member 4 are perpendicular to each other, so as to ensure that the anti-collision member can buffer the collision between the car 7 and the car frame column 5 in any direction.
[0031] See Figure 4 This utility model also provides an elevator car top fixing frame system, including at least two elevator car top fixing frames, a car 7, and four car frame columns 5. The car frame columns 5, first anti-collision members 3, and second anti-collision members 4 correspond one-to-one, and the anti-collision layers 25 of the first anti-collision members 3 and the second anti-collision members 4 abut against the corresponding car frame columns 5. By setting car top fixing members on both sides of the top of the car 7, a buffering effect is achieved between the car 7 and the car frame columns 5 on both sides, thereby reducing the noise generated during elevator operation.
[0032] Specifically, a top plate end cap 8 is provided above the car 7, and the top plate end cap 8 is connected to the bottom plate frame 1. By providing the top plate end cap 8, the elevator car top fixing frame can be stably connected to the top of the car 7.
[0033] As can be seen from the above, this utility model of elevator car top fixing bracket, through the use of base plate frame 1, first anti-collision member 3, and second anti-collision member 4, enables a flexible connection between the car 7 and the car frame column 5, reducing the noise generated by the car 7 and car frame column 5 during elevator operation and improving the passenger riding experience. Both the first anti-collision member 3 and the second anti-collision member 4 are fastened to the bent plate 2 by setting nuts 23 and bolts 24, thereby ensuring that the anti-collision layer 25 set on the head of the bolt 24 can be tightly attached to the bent plate 2. By setting a reinforcing plate 6, the connection between the bent plate 2 and the base plate frame 1 is made tighter. The reinforcing plate 6 is designed as a right-angled triangular prism, so that its contact surface with the bent plate 2 and the base plate frame 1 forms a 90° angle, making the entire elevator car top fixing bracket structure more stable and reliable. By setting a boss at the end of the bolt 24, maintenance personnel can use pliers to clamp the end of the bolt 24 to fix the anti-collision member, and then use a wrench to tighten the nut 23 to fix the anti-collision member to the bent plate 2.
[0034] In addition, this utility model also provides an elevator car top fixing frame system. By connecting each anti-collision component to the car frame column 5, the connection stability between the car frame column 5 and the elevator car top fixing frame is ensured. By connecting the bottom plate frame 1 to the top plate end cap 8 of the car 7, the car 7 can be connected to the car frame column 5, so as to realize the soft connection between the car 7 and the car frame column 5 by using this elevator car top fixing frame.
[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
