Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of elevator T-shaped hollow rail butt joint, and particularly relates to a novel elevator T-shaped hollow rail device. BACKGROUND

[0002] The elevator guide rail is an elevator component composed of a steel rail and a connecting plate. It is divided into car guide rails and counterweight guide rails. According to the cross-sectional shape, it is divided into three forms of T-shaped, L-shaped and hollow. The guide rail plays a guiding role while bearing the impact force of the car, the impact force of the elevator brake and the impact force of the safety gear emergency brake. The elevator guide rail is installed in the elevator shaft or between floors as two or more columns of vertical or inclined rigid rails to ensure that the car and the counterweight move up and down along the rails, and to ensure that the escalator and moving walkway steps move obliquely or horizontally along the rails. The guide rail provides guidance for the elevator car, counterweight device or steps. As can be seen from the definition of the guide rail, the guide rail is an important reference component of the vertical elevator, automatic elevator and moving walkway steps. It controls the running track of the elevator car, escalator and moving walkway steps and ensures the transmission of operation signals. It is an important component related to the safety and running quality of the elevator.

[0003] The T-shaped rail of the solid piece has a large overall weight, increasing the difficulty of hoisting and installing the counterweight guide rail. The T-shaped hollow rail is lighter and easier to install than the T-shaped rail of the solid piece. Therefore, the T-shaped hollow rail is applied more and more.

[0004] The guide rail of a conventional elevator usually needs to be connected by multiple guide rails. Due to manufacturing errors of the T-shaped guide rail and installation errors of the guide rail frame in the shaft, the upper and lower guide rails may be misaligned after installation, resulting in problems such as straightness error, torsion error and joint flatness. The step at the butt joint of the hollow T-shaped guide rail caused by misalignment cannot be polished and can only be adjusted on site. When misalignment occurs at the splicing position of the T-shaped hollow guide rail:

[0005] The fastening bolts between the T-shaped hollow guide rail and the connecting piece are loosened first. Then a gasket is inserted between the misaligned hollow T-shaped guide rail and the connecting piece (the gasket is placed according to the principle of "referring to the reference line, placing the gasket on the side that protrudes"). Finally, the fastening bolts are tightened again.

[0006] One side of the gasket is a flat surface, the other side is an inclined surface, and the thickness gradually increases. The thickness of the inserted gasket is controlled by the insertion depth. Since the gasket is inserted by the staff, the accuracy of the gasket is not easy to control. If the insertion thickness exceeds or does not reach the required thickness, the bolts need to be loosened again to adjust the insertion depth of the gasket. Therefore, it takes a lot of time to complete the final adjustment, which greatly affects the installation efficiency of the elevator guide rail. Based on this, in order to further improve the efficiency of the elevator guide rail splicing adjustment, a novel elevator T-shaped hollow rail device is provided. SUMMARY

[0069] The end surfaces of the track side seat 102, the fixed connecting block 202 and the clamping block 304 are provided with mounting holes 103, connecting holes 207 and through holes 305, the mounting holes 103, the connecting holes 207 and the through holes 305 are in an aligned state, and the inner wall diameters of the mounting holes 103, the connecting holes 207 and the through holes 305 are greater than the outer diameter of the screw rod of the external fastening bolt and less than the outer diameter of the nut;

[0070] The side edge sliding groove 203 and the E-shaped sliding groove 205 are symmetrically provided with two groups with the center line of the fixed connecting block 202 and the adjusting groove 208 as the center, and the clamping block 304, the E-shaped pad 401 and the adjusting assembly 5 are also correspondingly provided with two groups for matching the fixation of the two T-shaped hollow guide rails 1.

[0071] In the embodiment, when the two T-shaped hollow guide rails 1 are butt-jointed, the T-shaped connecting piece 2 is first connected with one T-shaped guide rail 1, the U-shaped butt-joint block 201 is aligned with the recessed part of the U-shaped rail head 101 and the T-shaped connecting piece 2 is pushed to move, finally the U-shaped butt-joint block 201 is inserted into the recessed part of the U-shaped rail head 101, and the track side seat 102 is located at the gap between the fixed connecting block 202 and the clamping block 304, when the mounting holes 103 on the track side seat 102 are aligned with the connecting holes 207 and the through holes 305, the external fastening bolt is sequentially inserted through the connecting holes 207, the mounting holes 103 and the through holes 305, then the nut is sleeved on the outside of the fastening bolt and the fastening bolt is tightened;

[0072] With the tightening of the fastening bolt, the clamping block 304 will be extruded by the nut to the direction of the fixed connecting block 202, and the clamping block 304 will simultaneously push the sliding block 301 to move, at this time, under the guidance of the inclined groove 3021 and the straight groove rod 303, the sliding block 301, the clamping block 304 as a whole are inclined to move to the direction of the U-shaped butt block 201, if the T-shaped hollow rail 1 is not in the centered state at this time, the inclined movement of the sliding block 301 will contact the side surface of the rail side seat 102 and push the rail side seat 102, so that the T-shaped hollow rail 1 moves to the centered state, when the sliding block 301 moves to the contact of the straight groove rod 303 and the longitudinal straight groove 3022, the T-shaped hollow rail 1 moves to the centered state, and at this time, through the guidance of the longitudinal straight groove 3022 and the straight groove rod 303, the subsequent movement of the sliding block 301 and the clamping block 304 is along the longitudinal straight line, so that the clamping block 304 completes the clamping operation on the rail side seat 102 (it needs to be supplemented that the outer wall width of the straight groove rod 303 matches the inner wall width of the inclined groove 3021, and the inclined angle of the cross section of the straight groove rod 303 is the same as the inclined angle of the inclined groove 3021, when the straight groove rod 303 is located inside the longitudinal straight groove 3022, the two arc surfaces of the straight groove rod 303 respectively fit the inner walls of the longitudinal straight groove 3022, so that the sliding block 301 moves according to the specified trajectory and does not deviate);

[0073] After completing the connection of the T-shaped connecting piece 2 and one T-shaped hollow rail 1, another T-shaped hollow rail 1 can be connected with the other end of the T-shaped connecting piece 2, and the operation is the same as the above operation, another T-shaped hollow rail 1 is inserted into the area between the other set of clamping blocks 304 and the fixed connecting block 202, and the fastening bolt is tightened for clamping operation, in this process, the T-shaped hollow rail 1 also automatically completes the centering operation, so that through the automatic centering of the two T-shaped hollow rails 1, the deviation of the butt joint of the two T-shaped hollow rails 1 can be effectively reduced;

[0074] After completing the butt joint of the two T-shaped hollow rails 1, the deviation of the butt joint of the two T-shaped hollow rails 1 is measured by external tools, if the deviation of the butt joint of the two T-shaped hollow rails 1 is too large and does not meet the standard, then the gasket assembly 4 can be used to fill the gasket between the protruding T-shaped hollow rail 1 back and the fixed connecting block 202, so as to eliminate the deviation;

[0075] When it is necessary to fill the gap between the back of the T-shaped hollow guide rail 1 and the fixed connecting block 202, the corresponding fastening bolt between the T-shaped hollow guide rail 1 and the fixed connecting block 202 can be loosened first, and then the external wrench is inserted into the polygonal hole on the side surface of the locking gear 501 and is pressed to make the locking gear 501 move and push the telescopic sleeve 502 to move. The telescopic sleeve 502 will move along the outer wall of the polygonal column 503 and press the spring 505 to contract. When the locking gear 501 moves away from the positioning tooth groove 2081 and enters the rotating groove 2082, the locking gear 501 can be twisted by the external wrench. The locking gear 501 drives the bolt 504 to rotate through the cooperation of the telescopic sleeve 502 and the polygonal column 503. The bolt 504 will move along the trajectory of the threaded groove 2084 and push the E-shaped pad 401. At this time, the E-shaped pad 401 moves along the inclined trajectory under the guidance of the inclined guide groove 402 and the cylindrical rod 403. The side of the E-shaped pad 401 close to the track side seat 102 will protrude from the fixed connecting block 202. Thus, the gap filling between the track side seat 102 and the fixed connecting block 202 is realized.

[0076] When the thickness of the E-shaped pad 401 protruding from the fixed connecting block 202 reaches the required thickness, the wrench can be removed. At this time, the locking gear 501 and the telescopic sleeve 502 will reset under the reset force of the spring 505. The locking gear 501 is clamped into the positioning tooth groove 2081. Thus, the locking of the locking gear 501 is realized. This can avoid the loosening of the bolt 504 in the subsequent process. Finally, the fastening bolt can be tightened.

[0077] Through the cooperation of the above-mentioned parts, unlike the traditional manual insertion of the gasket, the thickness of the E-shaped pad 401 is controlled by twisting the bolt 504. The thickness of the E-shaped pad 401 is easier to control, the overall operation efficiency is faster, and the overall area of the E-shaped pad 401 is larger than that of the traditional gasket. The position of the E-shaped pad 401 is fixed by the locking of the locking gear 501. This can effectively avoid the deviation of the gasket. Thus, unlike the traditional gasket, the E-shaped pad 401 has stronger supporting force and better supporting stability.

[0078] Please refer to Figures 1 to 4 , the outer wall size of the U-shaped butt block 201 is slightly smaller than the inner wall size of the U-shaped rail head 101.
