Description

Technical Field

[0001] This invention relates to the field of elevator guide rail technology, and specifically to an improved elevator guide rail. Background Technology

[0002] Elevator guide rails are the safety tracks for elevators to travel up and down in the shaft. The guide rails are installed on the shaft wall and are fixed to the shaft wall by guide rail brackets and guide rail supports. The most commonly used guide rails for elevators are "T"-shaped guide rails, which are characterized by high rigidity, high reliability, safety and low cost. The guide rail surface must be smooth and without obvious unevenness. Since the guide rails are the shuttle tracks for the guide shoes and safety brakes on the elevator car, the clearance must be ensured during installation.

[0003] Chinese patent application number (CN202210878632.2) discloses an improved elevator guide rail, including a guide rail block. Multiple connecting holes are provided on the upper and lower sides of the left surface of the guide rail block. Openings are provided on the left and right sides of the inner walls of the multiple connecting holes. Sliding grooves are provided on the left and right sides of the inner walls of the multiple openings. The inner walls of two corresponding sliding grooves are fixedly connected to inclined groove blocks through one side surface of a slider. Threaded rods are threadedly connected to the inner walls of the multiple inclined groove blocks.

[0004] The above solution solves the problem of fixing the elevator guide rail to the installation position of other equipment, thus avoiding the increased workload of maintenance personnel in frequently maintaining and testing the fixed position of the equipment. However, when tightening and limiting the bolts, the transmission structure is complex, the stability is poor during use, and there is no corresponding anti-reset structure. During use, the bolt clamping structure is prone to loosening, causing the bolt to be released. Therefore, an improved elevator guide rail is proposed. Summary of the Invention

[0013] 1. In this invention, the limiting card seat can move along the direction of the guide slide groove, and the limiting card plate on the inner wall of the limiting card seat can be adapted and engaged with the protrusion at one end of the interface. The limiting card plate can prevent the interface from loosening. At the same time, while the limiting card seat moves along the guide slide groove, the limiting pins at both ends of the guide cylinder can be adapted and engaged with the limiting slots on the limiting plate, thereby further fixing the position of the limiting card seat and further restricting the position of the limiting card seat to prevent it from loosening.

The transverse base 1 has mounting holes 101 extending through its upper and lower ends. The transverse base 1 can be fixedly connected to the inner wall of the elevator shaft via the mounting holes 101 using screws.

The guide rail 2 includes a connecting platform 201 formed on the guide rail 2 and a second mating interface 202 formed on the connecting platform 201. The guide rail 2 can be mated with the mating bolts 106 via the second mating interface 202, and the transverse base 1 and guide rail 2 can be fastened together via the first mating interface 105. The fastening mechanism can limit the position of the first mating interface 105 connecting the transverse base 1 and guide rail 2, thereby preventing the first mating interface 105 from loosening.

[0026] In this embodiment, specifically: the internal configuration of the mating bolt 106 includes a mating interface 105; the connecting platform 201 is adapted to the mating bolt 106 on the transverse base 1 via a mating interface 202; and the mating bolt 106 and the mating interface 202 are connected via the mating interface 105, with the end of the mating interface 105 forming...

[0027] It has a regular hexagonal protrusion, and the protrusion is adapted to the structural size and position of the limiting plate 301. The first interface 105 can pass through the butt bolt 106 on the transverse base 1 and the second interface 202 on the guide rail 2 respectively, and fasten the transverse base 1 and the guide rail 2. At the same time, the protrusion at the end of the first interface 105 can be adapted and engaged with the limiting plate 301 on the fastening mechanism, which can play a role in preventing the first interface 105 from loosening.

[0028] In this embodiment, specifically: the fastening mechanism includes a pair of guide grooves 102 formed on the transverse base 1, a pair of limiting plates 103 fixedly installed on the transverse base 1, limiting slots 104 formed on the limiting plates 103, and limiting seats 3 slidably installed on the guide grooves 102. A limiting plate 301 is fixedly installed on the inner wall of one end of the limiting seat 3, and a guide cylinder 302 is fixedly installed on the end of the limiting seat 3 away from the limiting plate 301. Limit pins 303 are slidably installed on both ends of the guide cylinder 302, and a spring is provided between the two limiting pins 303. The two ends of the spring are respectively fixedly connected to the two limiting pins 303 near each other. The limiting pins 303 and the limiting slots 104 are adapted in terms of structural size and position. The limiting pins 303 and the limiting slots 104 are engaged. The limiting seat 3 can move along the guide grooves 102. The device moves in a certain direction and can be fitted and engaged with the protrusion at the end of the interface 105 by the limiting plate 301 on the inner wall of the limiting plate 3. The limiting plate 301 can prevent the interface 105 from loosening. At the same time, while the limiting plate 3 moves along the guide groove 102, it can be fitted and engaged with the limiting slot 104 on the limiting plate 103 by the limiting pins 303 at both ends of the guide cylinder 302. This further fixes the position of the limiting plate 3 and restricts its position to prevent it from loosening.

[0029] In this embodiment, specifically: a sliding base 4 is mounted on the guide rail 2, and a guide pulley 401 is rotatably mounted on the sliding base 4. The sliding base 4 is slidably connected to the guide rail 2 through the guide pulley 401. A mating corner seat 402 is fixedly mounted on the side of the sliding base 4 away from the guide pulley 401. The sliding base 4 can be slidably connected to the guide rail 2 using the guide pulley 401, and can slide along the guide rail 2 using the guide pulley 401.

[0030] The movable sliding base 4 can be connected and installed with the elevator car through the docking angle seat 402, so as to facilitate the connection and use of the car.

Fastening mechanisms are provided at both ends of the transverse base 1. The guide rail 2 can be connected to the connecting bolt 106 through the second interface 202. The transverse base 1 and the guide rail 2 can be fastened together by means of the first interface 105. The fastening mechanism can limit the connection of the first interface 105 between the transverse base 1 and the guide rail 2, thereby preventing the first interface 105 from becoming loose.

[0032] Next, the first interface 105 can pass through the mating bolt 106 on the transverse base 1 and the second interface 202 on the guide rail 2 respectively, and fasten the transverse base 1 and the guide rail 2. At the same time, the protrusion at the end of the first interface 105 can be adapted and engaged with the limiting plate 301 on the fastening mechanism, which can play a role in preventing the first interface 105 from loosening.

[0033] Then, the limiting bracket 3 can move along the guide slide 102 and can be adapted and engaged with the protrusion at the end of the interface 105 through the limiting plate 301 on the inner wall of the limiting bracket 3. The limiting plate 301 can prevent the interface 105 from loosening. At the same time, while the limiting bracket 3 moves along the guide slide 102, it can be adapted and engaged with the limiting slot 104 on the limiting plate 103 through the limiting pins 303 at both ends of the guide cylinder 302. This further fixes the position of the limiting bracket 3 and further restricts the position of the limiting bracket 3 to prevent it from loosening.
