Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to an anchor bolt clamp reset mechanism. Background Technology

[0002] In the construction of tunnels and other projects, engineering trolleys are increasingly used to install anchor bolts. During installation, two clamps are typically used simultaneously to hold the anchor bolt, ensuring its stability during transfer and advancement. However, due to limitations in the working stroke and to further guarantee stability, in the actual advancement process, one clamp is usually moved synchronously with the anchor bolt for a short distance initially, then both clamps move synchronously with the anchor bolt, and finally, relative movement occurs between the clamps and the anchor bolt. After installation, the clamps are retracted. To facilitate this process, two drive sources are usually used to move the clamps. However, using two drive sources means occupying more space, which encroaches on the space of other components, so an improvement is necessary. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned prior art, this application provides an anchor bolt clamp reset mechanism, which can realize the separation and reset of the clamp through a single drive source, reducing space occupation and having strong practicality.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0005] An anchor bolt clamp reset mechanism includes: a push beam and a reset assembly.

[0006] The reset assembly includes a central shaft located on one side of the push beam and movable along its length. The axis of the central shaft is parallel to the length of the push beam and is fitted with two sleeves. Anchor clamps are provided on the sleeves. The sleeve away from the push end of the central shaft moves synchronously with the central shaft. The other sleeve is slidably fitted on the push beam and is movable along the axis of the central shaft.

[0007] Furthermore, the central shaft sleeve is provided with two guide sleeves, and the sleeve is located between the guide sleeves. The guide sleeve and the side of the sleeve near the central shaft propulsion end are each provided with two splicing plates. The splicing plates on the guide sleeve are installed on the propulsion beam, and the splicing plates on the sleeve are slidably engaged with the propulsion beam.

[0008] Furthermore, the reset assembly also includes a telescopic hydraulic cylinder arranged along the length of the push beam. The cylinder of the telescopic hydraulic cylinder is mounted in the central shaft, and the piston rod end of the telescopic hydraulic cylinder is connected to the mounting base, which is mounted on the push beam.

[0009] Furthermore, the side of the propulsion beam is provided with two connecting plates, and a guide rod is provided between the connecting plates. The side of the sleeve near the central shaft propulsion end is provided with a protruding plate, which is sleeved on the guide rod. A spring is sleeved on the guide rod, and the two ends of the spring abut against the protruding plate and the connecting plate located at the end of the propulsion beam, respectively, and are always in a compressed state.

[0010] Furthermore, a push ring is provided on the central shaft, which is located between the two sleeves and is used to push the sleeve near the advancing end of the central shaft.

[0011] The advantages of this invention are as follows: by setting a spring, the clamp near the central shaft pushing end always tends to move away from its pushing end, so that after the anchor bolt installation is completed, the clamp can move with the central shaft, thereby realizing the automatic reset of the clamp; and during the installation of the anchor bolt, the two clamps can move relative to each other and then move synchronously, ensuring the smooth installation of the anchor bolt, thereby realizing the movement of the clamp through a single drive source and reducing the space occupation.

[0012] The accompanying drawings described herein are merely illustrative of selected embodiments, not all possible implementations, and are not intended to limit the scope of this invention.

[0013] Figure 1 This is a three-dimensional schematic diagram of the overall structure of an embodiment of this application. Detailed Implementation

[0014] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0015] like Figure 1 As shown, this example provides an anchor clamp reset mechanism, including: a propulsion beam 1 and a reset assembly 2.

[0016] The reset assembly 2 includes a central shaft 21 located on one side of the push beam 1 and movable along its length. The axis of the central shaft 21 is parallel to the length of the push beam 1 and is fitted with two sleeves 22. Anchor clamps 3 are provided on the sleeves 22. The sleeve 22 away from the push end of the central shaft 21 moves synchronously with the central shaft 21, while the other sleeve 22 is slidably fitted on the push beam 1 and is movable along the axis of the central shaft 21.

[0017] Specifically, the central shaft 21 is fitted with two guide sleeves 23, and the sleeve 22 is located between the guide sleeves 23. The guide sleeves 23 and the sleeve 22 near the pushing end of the central shaft 21 are each provided with two splice plates 24. The splice plates 24 on the guide sleeves 23 are installed on the pushing beam 1. The splice plates 24 on the sleeve 22 are slidably engaged with the pushing beam 1. The guide sleeves 23 provide guidance for the movement of the central shaft 21 and also limit the stroke of the central shaft 21 to prevent it from moving too far.

[0018] Specifically, the reset assembly 2 also includes a telescopic cylinder 25 arranged along the length of the push beam 1. The cylinder of the telescopic cylinder 25 is installed in the central shaft 21, and the piston rod end of the telescopic cylinder 25 is connected to the mounting base 26. The mounting base 26 is installed on the push beam 1, and the central shaft 21 can be moved by the telescopic cylinder 25.

[0019] Specifically, a push ring 28 is provided on the central shaft 21. The push ring 28 is located between two sleeves 22 and is used to push the sleeve 22 near the pushing end of the central shaft 21. When the central shaft 21 moves, it will drive the anchor clamp 3 away from the pushing end of the central shaft 21 to move synchronously. After moving a certain distance, the push ring 28 abuts against the sleeve 22 near the pushing end of the central shaft 21. As the central shaft 21 continues to move, the two anchor clamps 3 will move synchronously, thereby completing the pushing of the anchor.

[0020] Specifically, the side of the propulsion beam 1 is provided with two connecting plates 11, and a guide rod 12 is provided between the connecting plates 11. The side of the sleeve 22 near the propulsion end of the central shaft 21 is provided with a protruding plate 27, which is sleeved on the guide rod 12. A spring 13 is sleeved on the guide rod 12. The two ends of the spring 13 abut against the protruding plate 27 and the connecting plate 11 at the end of the propulsion beam 1, respectively, and are always in a compressed state. Under the action of the spring 13, the sleeve 22 near the propulsion end of the central shaft 21 always tends to move away from the propulsion end of the central shaft 21. After the installation of the anchor rod is completed, the central shaft 21 is moved back, and the sleeve 22 near the propulsion end of the central shaft 21 will move back synchronously under the action of the spring 13 until the protruding plate 27 abuts against the connecting plate 11.

[0021] Since the above are merely preferred embodiments of this utility model and are not intended to limit this utility model, it is obvious that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
