AI Technical Summary
Traditional counterweight side-mounted high-speed elevators have large shaft widths and pit depths, resulting in high building and elevator costs.
A single set of compensating rope tensioning devices is adopted. By rationally arranging the position and connection method of the compensating rope tensioning devices, the compensating rope extends at an angle in the shaft. The car guide rail and counterweight guide rail are installed on the same common guide rail bracket, reducing the shaft width and pit depth.
This allows for the installation of elevators with smaller shaft widths and shallower pit depths, reducing elevator and building costs and improving practicality.

DETAILED DESCRIPTION
[0027] The preferred embodiments of the present application will be described in detail below with reference to the drawings, so that the advantages and features of the present application can be more easily understood by those skilled in the art, and the scope of protection of the present application can be more clearly defined.
[0028] As Figures 5-6 The present application provides a structure of a high-speed elevator with counterweight on the side, which comprises a shaft 1, a car 2, a counterweight 4, and a compensating rope tensioning device 6. The car 2, the counterweight 4, and the compensating rope tensioning device 6 are all installed in the shaft 1. The car 2 and the counterweight 4 are conventional devices of the prior art. Car guide rails 3 for guiding the car 2 to move up and down are installed on the left and right sides of the car 2 in the shaft 1. The two groups of car guide rails 3 have a spacing therebetween to form a spacing direction 9 on the horizontal plane. The aforementioned counterweight 4 is arranged on the left or right side of the car 2 and located at the rear side of the car guide rails 3, and can move up and down in the shaft 1.
[0029] The aforementioned compensating rope 62 tensioning device 6 is installed below the car 2 and the counterweight 4, and comprises tensioning wheels 61 and a compensating rope 62. The structure of the tensioning wheels 61 is of the prior art. The tensioning wheels 61 are installed on a base through bearings to be able to rotate around their central axes. At least two groups of tensioning wheels 61 are arranged at intervals from below the car 2 to below the counterweight 4. The bottom surfaces of the groups of tensioning wheels 61 are connected to each other to form a guide direction 91. The guide direction 91 is a straight line direction tangent to the bottom surfaces of the tensioning wheels 61. The projection of the aforementioned guide direction 91 on the horizontal plane forms an included angle with the spacing direction 9. The aforementioned compensating rope 62 has a tensioning extension section 621 extending along the guide direction 91 and in contact with the bottom surfaces of the groups of tensioning wheels 61, a first up-and-down extension section 622 extending upward from the leading end of the tensioning extension section 621 and connected to the car 2, and a second up-and-down extension section 623 extending upward from the trailing end of the tensioning extension section 621 and connected to the counterweight 4. Through the above structure design, the compensating rope 62 can be moved when the car 2 and the counterweight 4 move relative to each other.
[0030] Among them, the aforementioned tensioning wheels 61 are arranged at intervals in the horizontal direction, so that the guide direction 91 extends on the horizontal plane.
[0031] In the embodiment, counterweight guide rails 5 are arranged on both sides of the counterweight 4 in the hoistway 1 to guide the movement of the counterweight 4. A common guide rail bracket 8 is arranged on the front side of the counterweight 4 in the hoistway 1. The common guide rail bracket 8 is fixed to the side wall of the hoistway 1. In the arrangement, the common guide rail bracket 8 has a first assembly surface 81 facing the car 2 and a second assembly surface 82 facing the counterweight 4. A set of car guide rails is fixed to the first assembly surface 81, and a set of counterweight guide rails 5 is fixed to the second assembly surface 82. Through the above structure, the car guide rails and the counterweight guide rails 5 are fixed to the same common guide rail bracket 8, which can greatly reduce the width of the hoistway 1 occupied by the car guide rails 3 and the counterweight guide rails 5 during installation, effectively reducing the cost of the elevator and the building.
[0032] In the embodiment, the aforementioned tensioner 61 is arranged in two groups. The first upper and lower extension section 622 and the second upper and lower extension section 623 extend vertically or substantially vertically. The first group of tensioners 61 is located between the first upper and lower extension section 622 and the tensioning extension section 621 to guide the change of direction of the compensation rope 62. The second group of tensioners 61 is located between the second upper and lower extension section 623 and the tensioning extension section 621 to guide the change of direction of the compensation rope 62. Two groups of car buffers 21 are arranged on the left and right sides below the car 2. Two groups of counterweight buffers 41 are arranged on the front and back sides below the counterweight 4. The structure and function of the car buffers 21 and the counterweight buffers 41 are known in the art. The first group of tensioners 61 of the compensation rope tensioning device 6 is arranged between the two groups of car buffers 21, so that the compensation rope tensioning device 6 is arranged away from the car buffers 21. The second group of tensioners 61 of the compensation rope tensioning device 6 is arranged between the two groups of counterweight buffers 41, so that the compensation rope tensioning device 6 is arranged away from the counterweight buffers 41.
[0033] In use, the car 2 and the counterweight 4 move up and down relative to each other, driving the compensation rope 62 to move to achieve compensation. The counterweight 4 is arranged on the left rear side or the right rear side of the car 2. Through the cooperation of the compensation rope tensioning device 6, the guide direction 91 of the compensation rope tensioning device 6 and the spacing direction 9 of the two groups of car guide rails 3 are arranged at an angle in the horizontal plane to guide the extension of the compensation rope 62 and connect the car 2 and the counterweight 4. The compensation rope tensioning device 6 is arranged away from the car guide rails 3 and is not located below the car guide rails 3, so it is not necessary to raise the car guide rails 3 or deepen the pit. Through the combination of the above methods, a single group of compensation rope tensioning devices 6 is used, and the position and connection method of the compensation rope tensioning device 6 are reasonably arranged to meet the installation requirements of the elevator with a small width of the hoistway 1 and a small depth of the pit, which has strong practicality.
[0034] The above merely illustrates the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
