Description

Technical Field

[0001] This application relates to the field of elevator technology, specifically to a side counterweight elevator structure without counterweight guide rail support surface code. Background Technology

[0002] Traditional freight elevators typically have their main guide rails vertically aligned with the shaft's central axis. This classic layout effectively ensures the verticality and stability of the car's operation, demonstrating reliable guiding accuracy in typical applications. However, the guide rail support assembly (guide rail support bracket) required to support the centrally located main guide rail needs to extend and be fixed along the shaft's depth, occupying a significant amount of internal space and reducing the effective utilization of the shaft's space. Furthermore, the guide rail support assembly has numerous components, making installation cumbersome and requiring step-by-step inspection of multiple support layers during maintenance, which is time-consuming. This makes it particularly unsuitable for space-constrained environments such as older buildings. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes:

[0004] A side-counterweight elevator structure without counterweight guide rail support faceplates includes:

[0005] Well shaft;

[0006] The main guide rails are symmetrically and vertically arranged on the left and right side walls of the shaft. Each main guide rail on each side wall includes two side guide rails arranged at intervals along the front and back directions.

[0007] The car is installed in the hoistway and can be raised and lowered along the side guide rail. The bottom of the car is provided with two wheel pairs symmetrically arranged front and rear. Each wheel pair includes car guide wheels symmetrically arranged on the left and right sides at the bottom of the car.

[0008] The counterweight device is vertically mounted between two side guide rails on one side of the shaft, and the upper end of the counterweight device is provided with a counterweight guide wheel;

[0009] The traction machine is installed at the top of the shaft and has a traction sheave;

[0010] The traction rope is fixed at one end to the inner wall of the shaft, and the other end passes through two wheelsets, the traction sheave, and the counterweight guide sheave in sequence before being connected and fixed to the inner wall of the shaft.

[0011] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: a first anti-rope pulley is provided at the top of the shaft. The other end of the traction rope goes down and passes around a pulley pair, then goes up and passes around the first anti-rope pulley, then goes down and passes around another pulley pair, then passes around the traction pulley and the counterweight guide pulley in sequence, and is then connected and fixed to the inner wall of the shaft.

[0012] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the inner wall of the shaft has a second anti-rope sheave between two counterweight guide wheels, there are two counterweight guide wheels, the two counterweight guide wheels are arranged symmetrically front and back, and the traction rope passes through one of the counterweight guide wheels, the second anti-rope sheave and the other counterweight guide wheel in sequence.

[0013] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: it further includes a telescopic device and a pin. The telescopic device is installed on the upper beam of the car, and the pin is installed on the telescopic end of the telescopic device. A locking plate is provided in the shaft corresponding to each floor. The locking plate is provided with a socket that matches the pin.

[0016] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the upper end of the socket extends through the lock plate, and the width of the socket is greater than the width of the pin.

[0017] The beneficial effects of this utility model are as follows: The layout of the two wheelsets allows the weight of the car to be evenly and dynamically distributed to the front and rear wheels when carrying goods, providing stable support and initial guidance for the car. This eliminates the need for the car to rely on the traditional central guide rail layout to maintain balance. The guide rail is set on the side of the car in accordance with the front and rear wheel layout, and the guide rail is directly anchored to the pre-set installation position on the hoistway wall. This completely eliminates the dependence on guide rail brackets, reduces intermediate connection links, enhances connection rigidity, and reduces potential failure points, greatly improving operational reliability. The car's running sway is minimal, ensuring accurate and stable car running trajectory. It also ensures the safety of goods transportation, extends the overall service life of the freight elevator, and improves the stability and durability of the freight elevator in goods transportation operations. It frees up a large amount of hoistway space, which can be used to widen the cargo space inside the car or reserve more ample maintenance passages. Attached Figure Description

[0029] Reference Figure 1-6 This application proposes an embodiment of a side counterweight elevator structure without counterweight guide rail support face code, which includes:

[0030] Shaft 10;

[0031] The main guide rail 20 is symmetrically and vertically arranged on the left and right side walls of the shaft 10. Each main guide rail 20 on each side wall includes two side guide rails 21 arranged at intervals along the front and rear directions.

[0032] The car 30 is installed in the hoistway 10 and can be raised and lowered along the side guide rail 21. The bottom of the car 30 is provided with two wheel pairs symmetrically arranged front and rear. Each wheel pair includes car guide wheels 40 symmetrically arranged on the left and right sides at the bottom of the car 30.

[0033] The counterweight device 50 is vertically mounted between two side guide rails 21 on one side of the shaft 10, and the upper end of the counterweight device 50 is provided with a counterweight guide wheel 60.

[0034] The traction machine 70 is installed at the top inside the shaft 10 and has a traction sheave 80;

[0035] The traction rope 90 is fixed at one end to the inner wall of the shaft 10, and the other end passes through two wheelsets, the traction sheave 80, and the counterweight guide sheave 60 in sequence before being connected and fixed to the inner wall of the shaft 10.

[0036] The dual-wheel layout allows the car 30 to distribute its weight evenly and dynamically across the front and rear wheels when carrying cargo, providing stable support and initial guidance. This eliminates the need for the car 30 to rely on the traditional central guide rail 20 layout for balance. The car guide wheels 40 are all made of high-strength, wear-resistant polyurethane material, possessing excellent load-bearing capacity and vibration damping / noise reduction characteristics.

[0037] The main guide rail 20 conforms to the front and rear wheel layout and is set on the side of the car 30. The main guide rail 20 is made of high-precision cold-drawn steel and has high hardness and low friction surface characteristics. The side guide rail 21 directly anchors the main guide rail 20 to the preset installation position on the wall of the hoistway 10 through bolts, positioning pins and other connecting parts, completely eliminating the dependence on guide rail brackets, reducing intermediate connection links, enhancing connection rigidity, and reducing connecting parts is equivalent to reducing potential failure points, greatly enhancing operational reliability; the car 30 has minimal shaking during operation, ensuring the precise and stable running trajectory of the car 30; it ensures the safety of cargo transportation, extends the overall service life of the freight elevator, and improves the stability and durability of the freight elevator in cargo transportation operations; it frees up a large amount of space in the hoistway 10, which can be used to widen the internal cargo space of the car 30 or reserve more ample maintenance passages;

[0038] By reducing the number of purchased parts and eliminating the complex bracket installation process, the installation procedure is simplified, reducing procurement and construction costs. In subsequent maintenance, the simple structure also reduces the difficulty of repair and the cost of replacing parts.

[0039] The car 30 is mounted on two guide rails in a height-adjustable manner via guide shoes. The side counterweight is tightly fitted to one side of the car 30, saving space in the hoistway 10. Specifically, counterweight guide rails are installed on the sides of the two side guide rails 21 that are close to each other, and the counterweight device 50 is mounted on the two counterweight guide rails in a height-adjustable manner via guide shoes.

[0040] Based on the above, a first anti-rope pulley 11 is provided at the top of the shaft 10. The other end of the traction rope 90 goes down and passes around a pulley pair, then goes up and passes around the first anti-rope pulley 11, then goes down and passes around another pulley pair, then passes around the traction pulley 80 and the counterweight guide pulley 60 in sequence, and is then connected and fixed to the inner wall of the shaft 10. The traction rope 90 passes around the two pulley pairs in sequence through the guiding action of the first anti-rope pulley 11, so that the pulley pairs provide stable support and initial guidance for the car 30 when the car 30 is carrying goods.

[0041] Preferably, the inner wall of the shaft 10 has a second anti-rope pulley 12 between the two counterweight guide pulleys 60. There are two counterweight guide pulleys 60, which are arranged symmetrically front to back. The traction rope 90 passes through one of the counterweight guide pulleys 60, the second anti-rope pulley 12 and the other counterweight guide pulley 60 in sequence. The symmetrical arrangement of the two counterweight guide pulleys 60 ensures that the counterweight device 50 can be raised and lowered stably.

[0042] Because the traction rope 90 has a certain degree of extensibility, when the elevator car 30 stops at any floor and a loaded vehicle enters, the load inside the elevator car 30 exceeds the national standard of 0.85 times the rated load. For example, if a forklift enters the elevator car 30 to unload goods, it will cause the elevator car 30 to tilt.

[0043] Therefore, the elevator structure in this application also includes a telescopic device 100 and a pin 110. The telescopic device 100 is installed on the upper beam 130 of the car 30, and the pin 110 is installed on the telescopic end of the telescopic device 100. A locking plate 120 is provided in the shaft 10 corresponding to each floor. The locking plate 120 is provided with a socket 121 that matches the pin 110. The telescopic device 100 is used to extend and drive the pin 110 to be inserted into the socket 121, or to shorten so that the pin 110 is moved out of the socket 121.

[0044] In this embodiment, when the elevator car 30 stops at any floor, the telescopic device 100 extends into the socket 121 through the pin 110. The mutual locking of the pin 110 and the locking plate 120 enables the elevator to load normally even when the load exceeds the rated load, thus preventing the elevator car 30 from tilting due to the load exceeding the rated load. This allows the elevator to have the ability to exceed national standards when loaded at any floor and is more in line with actual usage needs.

[0045] Specifically, as shown in the attached drawings, the locking plate 120 is fixed with the side guide rails 21 on the same side by matching holes, making installation convenient.

[0046] Each end of the upper beam 130 is provided with two telescopic devices 100 and pins 110 arranged in pairs, and the locking plate 120 is provided with insertion holes 121 that match the two pins 110. Referring to the attached drawings, the four telescopic devices 100 and pins 110 can stably support the elevator load.

[0047] Preferably, the upper end of the socket 121 extends through the lock plate 120, and the width of the socket 121 is greater than the width of the pin 110.

[0048] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
