Technical Field

[0001] The utility model relates to the technical field of guide rail brackets, and particularly relates to a high-reliability U-shaped guide rail bracket. Background Technique

[0002] An elevator refers to a box body driven by power and running on rigid guide rails or a step running along a fixed line, and is an electromechanical device for lifting or horizontally transporting people and goods. Among them, an elevator guide rail is a vertical or inclined rigid guide rail installed in an elevator shaft or between floors, which ensures that the car moves up and down along it, and ensures that the steps of an escalator and a moving walk move obliquely or horizontally along it. During installation, a load-bearing beam is fixedly arranged on the well wall, and a guide rail bracket is fixedly installed on the load-bearing beam, and the guide rail bracket is used to support and connect the guide rail;

[0003] Most of the existing elevator guide rail brackets are fixedly set with the whole size, and it is difficult to freely adjust the installation size according to the specifications of the elevator shaft at the installation site and according to the requirements. This not only makes it inconvenient for on-site installation at the construction site, but also has a small scope of application.

[0004] Therefore, in view of this, the utility model proposes a high-reliability U-shaped guide rail bracket to make up for and improve the deficiencies of the existing technology. Content of the Utility Model

[0027] Embodiments of the present utility model

[0028] Please refer to Figures 1 to 5 As shown, a high-reliability U-shaped rail bracket includes a main crossbar 1 and a sub-crossbar 3 slidably connected thereto. A high-reliability U-shaped rail bracket includes:

[0029] Positioning holes 2, which are equidistantly arranged on the main crossbar 1;

[0030] Barrier blocks 4, which are fixedly connected to the inner wall of the sub-crossbar 3;

[0031] Locking component 7, which is arranged between the barrier block 4 and the positioning hole 2, and the locking component 7 is used to control the locking and unlocking of the main crossbar 1 and the sub-crossbar 3 so as to adjust the use length of the main crossbar 1 and the sub-crossbar 3;

[0032] Positioning grooves 5 are formed on the barrier block 4, and horizontal sliding grooves 6 are formed on the inner wall of the positioning grooves 5;

[0033] The locking component 7 includes a moving block 71 slidably connected to the horizontal sliding groove 6. One end surface of the moving block 71 close to the positioning hole 2 is fixedly connected with a bolt insertion rod 72. One end surface of the moving block 71 far from the positioning hole 2 is fixedly connected with a positioning column 73. The top end of the moving block 71 is fixedly connected with a shifting block 76;

[0034] The locking component 7 further includes a positioning tube 75 fixedly connected to the inner wall of the positioning groove 5, and the positioning tube 75 is slidably connected to the positioning post 73. A spring 74 is fixedly connected to the outer surface of the positioning tube 75, and one end of the spring 74 away from the positioning tube 75 abuts against the moving block 71;

[0035] A circular sliding hole is formed in the positioning groove 5, and a bolt inserting rod 72 is inserted and slidably connected through the circular sliding hole;

[0036] The diameter of the bolt inserting rod 72 is smaller than the diameter of the positioning hole 2, and the length of the bolt inserting rod 72 is smaller than the length of the positioning post 73;

[0037] With the above scheme: By the combined use of the shifting block 76 and the spring 74 and other structures, it is possible to control the shifting of the shifting block 76 away from or close to the spring 74, so that the moving block 71 drives the bolt inserting rod 72 and the positioning post 73 to move accordingly. When the bolt inserting rod 72 moves close to the spring 74 until the bolt inserting rod 72 completely disengages from the positioning hole 2 and is completely immersed in the positioning groove 5, at this time, the main crossbar 1 and the auxiliary crossbar 3 can be freely controlled to slide closer to or away from each other, so as to freely control the use length of the main crossbar 1 and the auxiliary crossbar 3. When the bolt inserting rod 72 moves away from the spring 74 until the bolt inserting rod 72 is inserted into the corresponding and adapted positioning hole 2, the main crossbar 1 and the auxiliary crossbar 3 are fixed for use, so that the staff can freely control the use length of the main crossbar 1 and the auxiliary crossbar 3 according to the needs, which not only facilitates the installation of the device at the construction site, but also expands the applicable range of the device.

[0038] Please refer to Figure 2 and Figure 3 As shown, connecting pieces 11 are fixedly connected to the outer surfaces of the main crossbar 1 and the auxiliary crossbar 3. A bottom code 8 is slidably connected to the outer surface of the connecting piece 11. Sliding grooves 10 are formed on both the connecting piece 11 and the bottom code 8, and a positioning bolt 9 is detachably installed on the sliding groove 10;

[0039] With the above scheme: By the combined use of the positioning bolt 9 and the sliding groove 10 and other structures, it is possible to control the bottom code 8 to slide closer to or away from the connecting piece 11, and cooperate with the locking of the positioning bolt 9 to control the use distance between the bottom code 8 and the connecting piece 11, so as to control the distance between the main crossbar 1 and the auxiliary crossbar 3 and the required fixing bracket, further improving the accuracy of the use size control of the device.

[0040] The working principle and usage process of the present utility model:

[0041] First, the staff presses the shifting block 76 to move it closer to the spring 74 for extrusion, causing the moving block 71 to carry the bolt inserting rod 72 and the positioning column 73 to move accordingly. At this time, the positioning column 73 moves towards the positioning tube 75 and sinks into it. While the moving block 71 moves to squeeze the spring 74 to contract, the bolt inserting rod 72 moves out of the positioning hole 2 until the bolt inserting rod 72 completely sinks into the positioning groove 5. At this time, the staff can freely control the use lengths of the main crossbar 1 and the auxiliary crossbar 3 according to requirements;

[0042] Subsequently, after the staff adjusts and confirms the use lengths of the main crossbar 1 and the auxiliary crossbar 3 according to the on-site installation environment, the pressed shifting block 76 is released. At this time, the spring 74 rebounds to its original position, causing the moving block 71 to carry the bolt inserting rod 72 and the positioning column 73 to move back to their original positions until the bolt inserting rod 72 inserts into the corresponding positioning hole 2 at this time, thereby fixing the installation lengths of the main crossbar 1 and the auxiliary crossbar 3;

[0043] Then, the staff detaches the positioning bolt 9 from the sliding groove 10, fixes the bottom code 8 to the guide rail, controls the distance between the connecting piece 11 and the bottom code 8 according to the use requirements. After the control and adjustment of the distance between the connecting piece 11 and the bottom code 8 are completed, the positioning bolt 9 is screwed through the sliding grooves 10 respectively opened on the connecting piece 11 and the bottom code 8 for fixation.

[0044] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
