Description

Technical Field

[0001] The utility model relates to the technical field of rock drilling jumbo, in particular to a wire rope anti - detachment structure for a rock drilling jumbo. Background Technique

[0002] A rock drilling jumbo (also known as a drilling jumbo) is a rock drilling equipment used in tunneling and underground engineering construction by the drill - and - blast method. It can move and support multiple rock drills to carry out drilling operations simultaneously. The working mechanism mainly consists of a thruster, a drill boom, a slewing mechanism, and a translation mechanism. Rock drilling jumbos can be divided into drift jumbos, mining jumbos, bolt jumbos, and open - pit rock drilling jumbos, etc.; according to the traveling mechanism of the drill jumbo, it can be divided into rail - wheel, tire, and crawler types; according to the number of rock drills installed, it can be divided into single - machine, double - machine, and multi - machine drill jumbos. The development status, working mechanism, classification, application, fault analysis, development trend, etc. at home and abroad are introduced in detail. When a rock drilling jumbo is in use, the wire rope needs to be firmly fixed.

[0003] The patent with the patent announcement number CN213326077U discloses a wire rope winding device, including a base, a rotating shaft is rotatably arranged on the base, the rotating shaft is horizontally arranged, and a winding motor for driving the rotating shaft to rotate is arranged on the base; one end of the rotating shaft is fixedly connected with a winding disc, four winding columns are arranged on the side of the winding disc away from the rotating shaft, the winding columns are evenly distributed around the axis of the winding disc, and a detachable baffle is arranged at the end of the winding column away from the winding disc. This application has the effect of facilitating the taking - out of the wire rope after uniform winding. The above - mentioned patent has the following deficiencies: Although this patent can wind the wire rope, it does not set up a mechanism to prevent the wire rope from unhooking. Therefore, the wire rope may unhook during the operation of the rock drilling jumbo, ultimately leading to safety accidents. In view of this, we propose a wire rope anti - detachment structure for a rock drilling jumbo. Content of the Utility Model

[0004] The purpose of the utility model is to provide a wire rope anti - detachment structure for a rock drilling jumbo to solve the problems raised in the above - mentioned background technique.

[0005] To achieve the above - mentioned purpose, the utility model provides the following technical solutions:

[0006] A wire rope anti - detachment structure for a rock drilling jumbo, including a box body, and an anti - unhooking mechanism is arranged inside the box body;

[0007] The anti - unhooking mechanism includes a vertical groove, a hydraulic cylinder, a hook, a first fixing block, a slot, a plug, a second fixing block, and a wire rope limiting groove;

[0008] The vertical groove is opened at the bottom of the box body. The top end of the hydraulic cylinder is fixedly connected to the inner wall of the top of the vertical groove, and the bottom end of the hydraulic cylinder is fixedly connected to the top end of the hook. The first fixing block is fixedly connected to the left inner wall of the vertical groove. The slot is opened at the bottom of the first fixing block. The inserting block is fixedly connected to the left end of the hook. The slot and the inserting block are inserted and connected. The inserting block is fixed by setting the slot.

[0009] Preferably, the number of the second fixing blocks is two. The two second fixing blocks are respectively fixedly connected to the front and rear sides of the vertical groove. The steel wire rope limiting groove is opened on one side where the two second fixing blocks face each other. The steel wire rope is limited by setting the steel wire rope limiting groove.

[0010] Preferably, an annular wire groove is opened on the outer wall of the box body. A winding mechanism is arranged on the left side of the box body. The winding mechanism includes a base. An annular sliding groove is opened on the right side of the base. Three sliding rods are slidably connected inside the annular sliding groove. The right ends of the sliding rods are fixedly connected to the left outer wall of the box body. The movement of the sliding rods is limited by setting the annular sliding groove.

[0011] Preferably, a motor is fixedly connected to the left side of the base. The right output end of the motor penetrates through the base and is fixedly connected to a transmission shaft. The right end of the transmission shaft is fixedly connected to the box body. The base provides a supporting force for the motor by setting the base.

[0012] Preferably, the left side of the base is fixedly connected to a mounting plate through a support rod. Mounting bolts are arranged on the mounting plate. The device is installed on the rock drilling jumbo by setting the mounting plate and the mounting bolts.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] First, hang the hanging ring on the steel wire rope on the hook. Then, start the hydraulic cylinder to drive the hook to move upward into the vertical groove, and the inserting block at the left end of the hook is inserted into the slot, thereby preventing the steel wire rope from unhooking and further improving the safety of the rock drilling jumbo during operation.

[0015] When the length of the steel wire rope is too long, the motor drives the transmission shaft to rotate. The rotation of the transmission shaft drives the box body to rotate. During the rotation of the box body, the fixed steel wire rope is wound through the wire groove, thereby preventing the length of the steel wire rope from being too long and affecting the normal construction of the rock drilling jumbo.
