Description

Technical Field

[0001] The utility model relates to the field of elevator bridge frames, in particular to a car frame diagonal tension plate assembly. Background Art

[0002] With the construction and development of high-rise buildings, elevators are widely used in buildings such as residences and buildings. The elevator car frame is a load-bearing component for the elevator car and its load. The elevator guide rails are fixed to the shaft wall with rail brackets. Guide shoes are installed on the upper beam and lower beam of the elevator car frame, and the guide shoes are stuck on the elevator guide rails to make the elevator car operate up and down along the guide rails. In the prior art, the installation of the elevator car and the elevator car frame is relatively difficult, and the structure between components is relatively complex, which is not convenient for disassembly, installation and maintenance. Many existing tie rod screw assemblies mainly consist of a tie rod and a plate, and the length of the tie rod is relatively long while the length of the plate is relatively short, resulting in high costs, the total length being non-adjustable or having a very small adjustment margin, and it is very easy to interfere with the control box and wire ropes in the car and cannot be installed.

[0003] After retrieval, Chinese Patent Publication No.: CN217894816U discloses an installation structure of a car frame diagonal tie rod, which relates to the technical field of elevator car frames. It includes a car bottom frame and columns used to form the car frame. An inclined tie rod for enhancing the stiffness of the car frame is arranged on the hypotenuse side between the car bottom frame and the columns. The lower end of the inclined tie rod is connected to the car bottom frame, and the upper end of the inclined tie rod is connected to the column through an adjustment and fixing mechanism to form a triangular diagonal tension structure. This utility model can reduce the outer dimensions of the car outside the corresponding positions of the control cabinet and the counterweight, and can realize a more compact layout of the shaft width, thereby realizing further optimization of the shaft layout.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figure 1 、 Figure 2 、 Figure 4 An embodiment provided by the present utility model: a diagonal tension plate assembly for a car frame, including a support frame 1. The support frame 1 is a prior art and can be implemented by those skilled in the art. Since it is a prior art, it will not be described in detail in this case. A connection block 2 is provided on the front surface of the right end of the support frame 1. The connection block 2 is a prior art and is fixed on the support frame 1 through the cooperation of bolts and nuts, facilitating the installation of the support assembly. A support assembly is provided on the right surface of the front end of the connection block 2, and a protection assembly is provided on the right surface of the rear end of the support assembly. The support assembly includes a second connecting plate 32. The second connecting plate 32 is fixedly connected to the connection block 2 through the cooperation of bolts and nuts. When the angle of the second connecting plate 32 needs to be adjusted, the nut can be loosened. The left surface of the rear end of the second connecting plate 32 is fixedly connected to the right surface of the front end of the connection block 2 through bolts. A first connecting plate 31 is slidably connected to the right surface of the second connecting plate 32. The connection distance between the first connecting plate 31 and the second connecting plate 32 can be adjusted to ensure its installation in environments of different sizes. In addition, the first connecting plate 31 is fixedly connected to the right surface of the front side of the bottom end of the support frame 1 through bolts and nuts, and the angle adjustment method is the same as that of the second connecting plate 32. A sealing groove 6 is provided on the right surface of the rear end of the second connecting plate 32, and the sealing groove 6 is opened outside the bolt hole where the second connecting plate 32 and the connection block 2 cooperate to ensure protection. A through hole 5 is provided on the front side of the right surface of the rear end of the second connecting plate 32 adjacent to the sealing groove 6. A fixing block 33 is fixedly connected to the right surface of the rear end of the first connecting plate 31.

[0032] Referring to Figure 2 、 Figure 4 The protection assembly includes a rotating column 43. The rotating column 43 is in interference fit with the inner wall of the through hole 5 to ensure the stability during rotation. The rotating column 43 is rotatably connected to the inner wall of the through hole 5. A round rod 42 is slidably connected through the right surface of the rotating column 43. The round rod 42 can prevent the spring 44 from bending when stretched. A protection shell 41 is fixedly connected to the right surface of the round rod 42. The protection shell 41 can be sleeved on the outer wall of the nut, which can prevent dust from entering between the nut and the bolt to a certain extent and has a certain degree of protection. A sealing ring 45 is fixedly connected to the left surface of the rear end of the protection shell 41. The sealing ring 45 is adapted to the sealing groove 6 to ensure the stability of the connection. The sealing ring 45 contacts the inner wall of the sealing groove 6.

[0033] Reference Figure 2 and Figure 3 The support assembly further includes a limit rod 35 which is slidably connected through the lower surface of the fixed block 33. There are multiple groups of grooves formed on the upper surface of the second connecting plate 32. The multiple groups of grooves provide limit points for the first connecting plate 31 and the second connecting plate 32 at different connection distances. The bottom end of the limit rod 35 contacts the inner wall of the groove. An L-shaped slide plate 34 which can ensure the stability of the movement of the limit rod 35 is fixedly connected to the upper surface of the limit rod 35, and the L-shaped slide plate 34 is slidably connected to the inner wall of the fixed block 33.

[0034] Reference Figure 2 and Figure 3 A guide block 36 is slidably connected to the inner wall of the fixed block 33 adjacent to the right side of the L-shaped slide plate 34. A rotating rod 39 is rotatably connected to the front surface of the guide block 36. The thread between the rotating rod 39 and the fixed block 33 can be self-locked to ensure that the rotating rod 39 will not rotate without external force, thus ensuring the stability of the guide block 36. The rotating rod 39 is threadedly connected through the front surface of the fixed block 33. A slide rod 38 is fixedly connected to the right surface of the bottom end of the L-shaped slide plate 34. A through groove 37 is formed on the right surface of the guide block 36, and the slide rod 38 is slidably connected to the inner wall of the through groove 37. The through groove 37 is inclined. The inclined setting ensures that when the guide block 36 moves, the slide rod 38 will drive the L-shaped slide plate 34 to move along its slope.

[0035] Reference Figure 2 and Figure 4 A spring 44 is sleeved on the outer wall of the round rod 42. The spring 44 always pulls the protective shell 41 to move leftward through its own elasticity to ensure the sealing performance of the protective shell 41. One end of the spring 44 is fixedly connected to the right surface of the rotating column 43, and the other end of the spring 44 is fixedly connected to the left surface of the front end of the protective shell 41. Multiple groups of protective components are provided. The multiple groups are provided to ensure that the bolts and nuts for fixing the first connecting plate 31 can also be protected, and the multiple groups of protective components are arranged on the right surface of the front end of the first connecting plate 31.

[0036] Working principle: when in use, the connecting plate 2 32 can be fixed to the connecting block 2 by bolts and nuts, and the connecting plate 1 31 can also be fixed to the front side of the bottom end of the support frame 1. When the connection distance between the connecting plate 1 31 and the connecting plate 2 32 needs to be adjusted, the rotating rod 39 can be rotated. Since the rotating rod 39 and the fixing block 33 are threadedly matched, the rotating rod 39 will move forward, and at the same time, a rotation connection will occur between the rotating rod 39 and the guide block 36, and the guide block 36 will also be mobilized to move. At this time, the sliding rod 38 will move along the inclination of the through groove 37, and the sliding rod 38 will drive the L-shaped slide plate 34 to move, and the L-shaped slide plate 34 will drive the limit rod 35 to move and disengage from the inner wall of the groove. At this time, the connection distance between the connecting plate 1 31 and the connecting plate 2 32 can be adjusted. After the adjustment is completed, the rotating rod 39 can be rotated in the opposite direction. The subsequent structural matching method is the same as above, but the direction of movement of some structures is opposite to that of the above.

[0037] After the connecting plate 2 32 and the connecting plate 1 31 are fixed with nuts and bolts, the connection between the nuts and the bolts can be protected by the provided protective assembly. It is only necessary to pull the protective shell 41, the protective shell 41 will stretch the spring 44, and then push the protective shell 41 to rotate. The protective shell 41 will drive the rotating column 43 to rotate through the round rod 42 until the protective shell 41 overlaps with the nut. At this time, the protective shell 41 is loosened, and the spring 44 will pull the protective shell 41 to move in the opposite direction through its own elasticity, and the sealing ring 45 will also move accordingly and insert into the inner wall of the sealing groove 6.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
