Description

Technical Field

[0001] This utility model relates to a bracket, and more particularly to a retractable elevator guide rail bracket. Background Technology

[0002] Elevator guide rails, divided into car guide rails and counterweight guide rails, serve a guiding function and withstand the impact force during elevator braking. Elevator guide rail frames are components used to support and fix the car and counterweight guide rails. They are installed on the shaft wall or beams, fixing the spatial position of the guide rails and bearing various movements from them.

[0003] Existing counterweight guide rail frames, such as the Chinese utility model patent with publication number CN205151446U, disclose a freight elevator counterweight combined guide rail frame, including: a guide rail frame and a counterweight guide rail support frame, wherein there are two counterweight guide rail support frames, which are respectively installed at both ends of the guide rail frame; a counterweight guide rail frame base code is installed on the counterweight guide rail frame base code, and at least two expansion bolts are installed on the counterweight guide rail frame base code; a counterweight pressure guide plate connector is installed on the inner side of the counterweight guide rail support frame; a car pressure guide plate connector is installed on the outer side of the guide rail frame; the guide rail frame and the counterweight guide rail support frame are connected by a bracket connector.

[0004] The aforementioned counterweight guide rail frame has a fixed distance between the two counterweight guide rail support frames, which can only meet the guide rail installation under certain shaft space and elevator size conditions. It is difficult to adjust the position of the guide rail, making the installation of the guide rail quite limited. Even if the guide rail frame is designed as an adjustable structure, the existing guide rail frame can only be adjusted in a small range in one direction. The adjustment range is narrow, the adjustment direction is relatively singular, and the use is not flexible enough, affecting the stress deformation of the guide rail. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention employs two symmetrical L-shaped counterweight guide rail brackets, with an adjustment bracket connected to one end of each bracket via multiple elongated holes. The other end of each bracket is connected to a first fixed bracket via multiple elongated holes.

[0024] Example:

[0025] like Figures 1-5 As shown, a retractable elevator guide rail bracket includes a first guide rail bracket 1 and a second guide rail bracket 2 distributed left and right. The first guide rail bracket 1 includes a pair of symmetrically distributed L-shaped counterweight guide rail brackets 11. An adjusting bracket 12 is provided between the inner ends of the two counterweight guide rail brackets 11. The adjusting bracket 12 is provided with a first connecting bracket 13 for installing the car guide rail 4. The counterweight guide rail bracket 11 is provided with a second connecting bracket 14 for installing the counterweight guide rail. The outer ends of the two counterweight guide rail brackets 11 are each provided with a first fixed bracket 15 connected to the shaft wall. The counterweight guide rail bracket 11, the adjusting bracket 12 and the first fixed bracket are each provided with a plurality of inclined elongated holes 16 that cooperate to connect. The second guide rail bracket 2 includes a third connecting bracket 21 for installing the car guide rail 4 and a second fixed bracket 22 connected to the shaft wall. The second fixed bracket 22 and the third connecting bracket 21 are each provided with strip holes 23 that cooperate to connect vertically.

[0026] This invention employs two symmetrical L-shaped counterweight guide rail brackets 11, with one end of each bracket connected by an adjusting bracket 12 and multiple inclined elongated holes 16. This allows the two counterweight guide rail brackets 11 to move along the length of the adjusting bracket 12, thereby adjusting the distance between them. The other end of each counterweight guide rail bracket 11 is connected to a first fixed bracket 15 via multiple elongated holes 16. The first fixed bracket 15 can move along the counterweight guide rail bracket 11, thereby adjusting the distance between it and the adjusting bracket 12. Furthermore, this invention employs two second fixed brackets 22 and a third connecting bracket 21 connected vertically by strip-shaped holes 23. The second fixed brackets 22 and the third connecting bracket 21 can be adjusted in a direction perpendicular to the car guide rail 4, thereby adjusting the installation distance between the two car guide rails 4.

[0027] Therefore, this utility model can achieve multi-directional and wide-range adjustments, making it easy for the guide rail to be installed in different environments, and it is convenient and flexible to use.

[0028] Both the first fixed bracket 15 and the second fixed bracket 22 have elongated vertical holes 24 and elongated horizontal holes 25 on their sides. Expansion bolts 26 for connection to the well wall are installed in both the elongated vertical holes 24 and elongated horizontal holes 25. The expansion bolts 26 are connected to the well wall by being installed in multiple elongated vertical holes 24 and elongated horizontal holes 25 of different shapes, thereby expanding the range of guide rail brackets and guide rail installation.

[0029] The second fixed bracket 22 and the third connecting bracket 21 have the same structure. Using two identical structures to form the telescopic and adjustable second guide rail bracket 2 makes manufacturing easier, shortens the component manufacturing cycle, and saves manufacturing costs.

[0030] A buffer assembly 3 is provided between the first connecting frame 13 and / or the third connecting frame 21 and the car guide rail 4. The buffer assembly 3 reduces the vibration of the car guide rail 4, decreases the vibration sensation during car operation, and improves the smoothness of car operation.

[0031] The buffer assembly 3 includes a first mounting member 31 that is movably connected to the first connecting frame 13 or the third connecting frame 21. A first buffer body 32 is provided between the first mounting member 31 and the first connecting frame 13 or the third connecting frame 21. A second mounting member 33 is movably connected inside the first mounting member 31. A second buffer body 34 is provided between the second mounting member 33 and the first mounting member 31. A third buffer body 35 is provided inside the second mounting member 33. The third buffer body 35 is connected to the car guide rail 4. The car guide rail 4 is buffered by multiple buffer structures, including a first buffer body 32, a second buffer body 34, and a third buffer body 35, between it and the first connecting frame 13 or the third connecting frame 21. When the car guide rail 4 is subjected to impact force, the third buffer body 35 first buffers and reduces vibration, weakening the vibration transmitted from the car guide rail 4 to the second mounting member 33. If the vibration of the second mounting member 33 is still strong, the second buffer body 34 buffers and reduces vibration, weakening the vibration transmitted from the car guide rail 4 to the first mounting member 31. If the vibration of the first mounting member 31 is still strong, the first buffer body 32 buffers and reduces vibration, thus achieving layer-by-layer buffering of the car guide rail 4 and rapid reset of the car guide rail 4. This avoids vibration damage, vibration noise, or positional displacement of the car guide rail 4 under large impact, thereby reducing the noise of elevator operation and improving the smoothness of elevator operation.

[0032] The third buffer 35 can be made of rubber, latex, etc., to absorb vibration and noise.

[0033] The first connecting frame 13 or the third connecting frame 21 is provided with a fixed sleeve 36 on its side. The first buffer body 32 includes a first movable rod 321 that is slidably connected between the fixed sleeve 36 and the first mounting member 31. A first buffer spring 322 is sleeved on the outside of the first movable rod 321. One end of the first buffer spring 322 is connected to the first mounting member 31, and the other end of the first buffer spring 322 is connected to the fixed sleeve 36.

[0034] The second buffer body 34 includes a second movable rod 341 slidably connected between the second mounting member 33 and the first mounting member 31. A second buffer spring 342 is sleeved on the outside of the second movable rod 341. One end of the second buffer spring 342 is connected to the second mounting member 33, and the other end of the second buffer spring 342 is connected to the first mounting member 31. The first movable rod 321 and the second movable rod 341 restrict the movement direction of the first mounting member 31 and the second mounting member 33. The first buffer spring 322 and the second buffer spring 342 achieve the function of buffering and resetting the car guide rail 4.

[0035] The second mounting component 33 has symmetrically connected, via adjusting bolts 371, to two sides of a fixed counterweight guide rail, with locking blocks 377 on opposite sides. The locking blocks 37 have slots 372 on opposite sides for the car guide rail 4 to be inserted into. This invention further secures the car guide rail 4 by using the locking blocks 37, preventing it from shifting forward or backward. Even if the car guide rail 4 becomes loose after prolonged use, the distance between the two locking blocks 37 can be adjusted using the adjusting bolts 371 for further tightening, thus improving the stability of the car guide rail 4.

[0036] The aforementioned buffer component 3 can also be installed between the second connecting frame 14 and the counterweight guide rail, thereby achieving the buffering and noise reduction effect on the counterweight guide rail.

[0037] The parts of this utility model not described in detail are existing technologies and therefore will not be specifically described here.
