Description

Technical Field

[0001] The present application relates to the technical field of elevator guide rails, and in particular to an elevator guide rail bracket. Background Art

[0002] Elevator guide rail brackets are important components used to fix elevator guide rails. Their function is to support and fix the guide rails to ensure the safety and stability of elevator operation. Guide rail brackets are usually made of steel and have strength and stability. The design and installation of guide rail brackets need to follow relevant industry standards and specifications to ensure that they can withstand the operating load and impact force of the elevator. The form and structure of guide rail brackets vary depending on the type of elevator. For example, the design of guide rail brackets for elevators and escalators may be slightly different. The installation of guide rail brackets must comply with relevant construction specifications to ensure that they are safe and reliable and easy to maintain and repair.

[0003] In the Chinese patent with application number 202122839350.5, an elevator guide rail bracket is disclosed. Through the positioning rod, the adjusting screw and the hinge assembly structure, the distance between the two sets of adjustment boxes can be adjusted according to the length of the elevator guide rail, which is convenient for the bracket body to connect and fix the two ends of the elevator guide rail. The elevator guide rail that is offset from the installation track can be corrected, thereby ensuring the normal operation of the elevator car.

[0004] With regard to the above-mentioned related technologies, the inventors believe that during the actual use of the above-mentioned device, since the elevator will generate vibrations during the up and down movement, when the vibrations are transmitted to the bracket through the guide rails, it is easy to cause the two sets of clamping arms to loosen on the positive and negative screws, resulting in the inability to effectively support the guide rails, posing certain safety hazards.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0006] In order to solve the problem that when vibration is transmitted to the bracket through the guide rail, the two sets of clamp arms are easily loosened on the forward and reverse screws, resulting in the inability to effectively support the guide rail, the present application provides an elevator guide rail bracket.

[0007] The present application provides an elevator guide rail bracket adopting the following technical solution:

[0008] An elevator guide rail bracket comprises a guide rail body, a bracket body is arranged on the guide rail body, the bracket body comprises a fixed block, two groups of clamping blocks are arranged on the fixed block, two groups of support frames are symmetrically installed on both sides of the fixed block, two groups of support rods are fixedly installed on the clamping blocks, and limiting mechanisms are arranged on the support rods.

[0009] Preferably, a guide groove is provided on the fixing block, and a guide block cooperating with the guide groove is fixedly mounted on the clamping block.

[0010] Preferably, forward and reverse screw rods are rotatably mounted on the fixed block, and the forward and reverse screw rods are respectively matched with the two groups of guide blocks.

[0011] Preferably, the limiting mechanism comprises a plurality of teeth mounted on the supporting frame, and gears cooperating with the teeth are arranged in the supporting frame.

[0012] Preferably, threaded holes are provided on the gears, a threaded rod that cooperates with the threaded holes is rotatably provided on the support rod, and the threaded rod cooperates with the support rod.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] By rotating the forward and reverse screw rods to control the two groups of guide blocks to move in opposite directions, the two groups of clamping blocks are driven to approach each other to support the slide rail, and then the gear is pulled out of the support frame, the position where the threaded hole and the threaded rod match is selected to reinsert the gear, and then the threaded rod is rotated to insert the threaded rod into the threaded hole, and finally the bracket is installed on the inner wall of the elevator shaft. When the two groups of clamping blocks tend to loosen, the two groups of support rods will be driven to move, and the support rods will drive the threaded rods to move. The gears and teeth cooperate with each other to block the movement of the threaded rods, thereby preventing the clamping blocks from loosening, thereby improving the stability of the bracket's support for the slide rail and improving the safety of the device.

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses an elevator guide rail bracket. Figure 1-3, an elevator guide rail bracket, comprising a guide rail body 1, a bracket body 2 is arranged on the guide rail body 1, the bracket body 2 comprises a fixed block 3, two groups of clamping blocks 4 are arranged on the fixed block 3, two groups of support frames 5 are symmetrically installed on both sides of the fixed block 3, two groups of support rods 6 are fixedly installed on the clamping block 4, and the support rods 6 are all provided with a limiting mechanism, a guide groove 7 is opened on the fixed block 3, and a guide block 8 matched with the guide groove 7 is fixedly installed on the clamping block 4, and a positive and negative screw rod 9 is rotatably installed on the fixed block 3, and the positive and negative screw rods 9 are respectively matched with the two groups of guide blocks 8;

[0021] By adopting the above technical solution, the forward and reverse screw rods 9 are rotated, and through the guiding effect of the guide grooves 7, the forward and reverse screw rods 9 will drive the two groups of guide blocks 8 to move in opposite directions, and through the guide blocks 8, the two groups of clamping blocks 4 are driven to approach each other and cooperate with the slide rails, thereby supporting the slide rails.

[0022] Reference Figure 1-3 The limiting mechanism includes a plurality of teeth 10 mounted on the support frame 5, and gears 11 cooperating with the teeth 10 are arranged in the support frame 5, and threaded holes 12 are opened on the gears 11, and threaded rods 13 cooperating with the threaded holes 12 are rotatably arranged on the support rods 6, and the threaded rods 13 cooperate with the support rods 6;

[0023] By adopting the above technical solution, after the clamping block 4 supports the slide rail, the gear 11 is pulled out from the support frame 5, and the position where the threaded hole 12 and the threaded rod 13 cooperate is selected to reinsert the gear 11, and then the threaded rod 13 is rotated so that the threaded rod 13 is inserted into the threaded hole 12, and finally the bracket is installed on the inner wall of the elevator shaft. When the two groups of clamping blocks 4 tend to loosen, the two groups of support rods 6 will be driven to move, and the support rods 6 drive the threaded rods 13 to move.

[0024] The implementation principle of an elevator guide rail bracket in the embodiment of the present application is as follows: first, the forward and reverse screw rods 9 are rotated to control the two groups of guide blocks 8 to move in opposite directions, thereby driving the two groups of clamping blocks 4 to approach each other to support the slide rail, and then the gear 11 is pulled out from the support frame 5, and the position where the threaded hole 12 and the threaded rod 13 cooperate is selected to reinsert the gear 11, and then the threaded rod 13 is rotated so that the threaded rod 13 is inserted into the threaded hole 12, and finally the bracket is installed on the inner wall of the elevator shaft. When the two groups of clamping blocks 4 tend to loosen, they will drive the two groups of support rods 6 to move, and the support rods 6 drive the threaded rod 13 to move. Through the cooperation between the gear 11 and the teeth 10, the movement trend of the threaded rod 13 can be blocked, thereby preventing the clamping block 4 from loosening, which has the effect of improving the stability of the bracket's support for the slide rail and improving the safety of the device.
