Abstract
Description
Technical Field
[0001] This utility model belongs to the field of anchor bolt trolley technology, specifically relating to a self-locking mechanism for an anchor bolt storage unit. Background Technology
[0002] Currently, the technology level, construction equipment, and domestic production of rapid construction equipment for soft rock tunnels in my country's railway and highway construction are still in the early stages of tunnel construction mechanization, and the overall technology lags behind that of developed countries. The anchor bolt magazine, as the storage and transfer point for anchor bolts on the anchor bolt trolley, is crucial. For example, application number 2019209259823, entitled "An Anchor Bolt Magazine Component for Anchor Bolt Trolley," discloses an anchor bolt magazine that enables rapid and efficient intermittent feeding of anchor bolts.
[0003] After the anchor bolts are placed in position, a pause is needed while the robotic arm picks them up. During this pause, a self-locking mechanism is required to ensure the anchor bolts remain in place for proper gripping. A common method for this is to use a separate hydraulic self-locking mechanism. While this method fulfills the self-locking requirement, it is structurally complex and increases equipment costs. Utility Model Content
[0004] To address the issue that existing self-locking mechanisms are complex and increase equipment costs, a self-locking mechanism for anchor bolt storage is provided.
[0005] A self-locking mechanism for an anchor bolt magazine includes a hydraulic motor, an anchor bolt chuck, an indexing gear, a transmission crank, a transmission shaft, a cam, a chuck, and a frame. The transmission shaft is rotatably mounted on the frame. The anchor bolt chuck, indexing gear, and chuck are all mounted on the transmission shaft. The chuck has a locking hole. The hydraulic motor is mounted on the frame. The transmission crank and cam are respectively mounted on the output shaft of the hydraulic motor. A mounting bracket is mounted on the frame. A locking rod is mounted on the mounting bracket and can slide up and down. A stop plate is fixedly mounted on the lower end of the locking rod. A spring is fitted on the locking rod, located between the stop plate and the mounting bracket. The lower end of the locking rod contacts the cam. When the locking rod moves upward, it can be inserted into the locking hole.
[0006] Preferably, a roller is provided at the lower end of the locking rod.
[0007] The beneficial effects of this utility model are:
[0008] The design is integrated with the drive mechanism, eliminating the need for a separate hydraulic cylinder, resulting in a simple and compact structure. Attached Figure Description

[0012] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.
[0013] See Figures 1-3 This embodiment provides a self-locking mechanism for an anchor bolt magazine.
[0014] The system includes a hydraulic motor 1, an anchor bolt chuck 2, an indexing gear 3, a transmission crank 4, a transmission shaft 5, a cam 6, a chuck 7, and a frame 10. The transmission shaft 5 is rotatably mounted on the frame 10. The anchor bolt chuck 2, the indexing gear 3, and the chuck 7 are all mounted on the transmission shaft 5. The chuck 7 has a locking hole 71. The hydraulic motor 1 is mounted on the frame 10. The transmission crank 4 and the cam 6 are respectively mounted on the output shaft 11 of the hydraulic motor 1. The mounting bracket 81 is mounted on the frame 10. The locking rod 82 is mounted on the mounting bracket 81 and can slide up and down. A baffle 83 is fixedly mounted on the lower end of the locking rod 82. A spring is fitted on the locking rod 82 and is located between the baffle 83 and the mounting bracket 81. The lower end of the locking rod 82 contacts the cam 6. When the locking rod 82 moves upward, it can be inserted into the locking hole 71.
[0015] like Figure 3 As shown, a roller 84 is provided at the lower end of the locking rod 82.
[0016] Explanation of the self-locking principle, such as Figure 2 As shown, the hydraulic motor 1 rotates one revolution, shifting the indexing gear 3 to a certain angle. It can be seen from the diagram that the lever of the transmission crank 4 and the highest point of the cam 6 are at a 180-degree angle. When the shifting begins, the spring on the locking rod 82 pushes the locking rod 82 downwards, causing the upper end of the locking rod 82 to be pulled out of the retaining hole 71, thus shifting the indexing gear 3 and driving the transmission shaft 5 to rotate. During the rotation of the hydraulic motor, the cam 6 also rotates. When the indexing gear 3 reaches its position, the highest point of the cam 6 contacts the lower end of the locking rod 82, causing the cam 6 to push the locking rod 82 upwards, inserting its upper end into the retaining hole 71, thus limiting and locking the transmission shaft 5.
[0017] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "clockwise" and "counterclockwise" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0018] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
