Description

Technical Field

[0001] This utility model relates to the technical field of gate lock device, and in particular to a hydraulic tool for engaging and disengaging gate lock. Background Technology

[0002] The existing gate locking device's locking mechanism is a rocker arm-linkage structure, see... Figure 2 The gate lock is engaged or disengaged by manual pushing and pulling of the locking arm, which in turn pushes the locking shaft via a connecting rod. The locking shaft weighs approximately 0.5 tons and is constantly exposed to wind and rain, resulting in poor lubrication and significant resistance during engagement and disengagement. Existing gate lock engagement and disengagement devices rely on relatively low manual operating force; the driving force provided by the rocker arm-connecting rod mechanism is far less than the required force for engagement and disengagement, making the engagement and disengagement of the gate lock difficult.

[0024] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0025] To achieve the above-mentioned technical features, the purpose of this utility model is as follows:

[0026] See appendix Figure 1 , Figure 3-6 A hydraulic tool for engaging and disengaging a gate lock includes a mounting frame 1 and a hydraulic drive unit 2. The mounting frame 1 includes a crossbeam 1a, on which two support arms 1b are mounted. The support arms 1b are connected to the lock frame 4 of the lock device via a first connecting part 3. The hydraulic drive unit 2, mounted on the crossbeam 1a, is connected to the lock shaft 6 of the lock device via a second connecting part 5. During operation, the lock shaft 6 moves linearly along its own axis under the drive of the hydraulic drive unit 2.

[0027] The hydraulic tool provided in this embodiment includes a mounting frame 1 and a hydraulic drive unit 2. The mounting frame 1 includes a crossbeam 1a, on which two support arms 1b are mounted. The ends of the support arms 1b are equipped with first connecting parts 3. During operation, the first connecting parts 3 are first connected to the locking frame 4 of the locking device to complete the erection of the mounting frame 1 and prepare for the installation of the hydraulic drive unit 2. Then, the hydraulic drive unit 2 is installed on the crossbeam 1a, and the drive end of the hydraulic drive unit 2 is connected to the locking shaft 6. Subsequently, the hydraulic drive unit 2 drives the locking shaft 6, causing the locking shaft 6 to move linearly along its own axis to complete the insertion or withdrawal of the gate locking. Compared with the manual drive method using a rocker arm mechanism in the prior art, the operation is simpler and less labor-intensive.

[0028] In one embodiment, the first connecting part 3 includes a connecting block 3a. The connecting block 3a is provided with a slot 3b that mates with the locking frame 4. The connecting block 3a is provided with a fastening bolt 3c. The end of the fastening bolt 3c extends into the slot 3b and abuts against the locking frame 4. The slot 3b on the connecting block 3a mates with the locking frame 4. Then, by tightening the fastening bolt 3c, the installation of the connecting block 3a can be completed, thereby fixing the support arm 1b and the crossbeam 1a on the locking frame 4.

[0029] In one implementation, in this embodiment, the hydraulic drive unit 2 is a hydraulic cylinder, and the fixed end of the hydraulic cylinder is connected to the crossbeam 1a. (See [reference]). Figure 6 The second connecting part 5 includes a connecting seat 5b, which is hinged to the ear plate 6a at the end of the locking shaft 6. The telescopic end of the hydraulic cylinder is connected to the connecting seat 5b. The locking shaft 6 can be moved along its own axis by pushing or pulling the hydraulic cylinder to complete the insertion or withdrawal of the gate locking spindle.

[0030] Preferably, the axis of the hydraulic cylinder coincides with the axis of the locking shaft 6, so that the force output by the hydraulic cylinder is output along the axis of the locking shaft 6, making it easier for the hydraulic cylinder to push or pull the locking shaft 6.

[0031] In one embodiment, the second connecting part 5 includes a guide rod 5a vertically mounted on the crossbeam 1a. A connecting seat 5b is mounted on the first end of the guide rod 5a, and the connecting seat 5b is hinged to the ear plate 6a at the end of the locking shaft 6. The guide rod 5a passes through the crossbeam 1a, and a limit nut 5c is mounted on the second end of the guide rod 5a. The hydraulic drive unit 2 is a hollow hydraulic jack mounted on the outside of the guide rod 5a. When the hydraulic tool in this embodiment performs the gate locking operation, see... Figure 4 A hollow hydraulic jack is installed between the connecting seat 5b and the crossbeam 1a. At this time, one end of the guide rod 5a is connected to the connecting seat 5b, and the ear plate 6a at the end of the locking shaft 6 is hinged. The guide rod 5a provides guidance and support for the hollow hydraulic jack. As the moving end of the hollow hydraulic jack extends and abuts against the connecting seat 5b, it pushes the locking shaft 6, completing the engagement of the gate locking pin. When the hydraulic tool in this embodiment performs the gate locking pin withdrawal operation, see... Figure 5 The hollow hydraulic jack is installed at the end of the guide rod 5a away from the connecting seat 5b. The first end of the guide rod 5a is connected to the connecting seat 5b. The second end of the guide rod 5a is installed with a limit nut 5c near the moving end of the hollow hydraulic jack. The limit nut 5c limits the hollow hydraulic jack. The ear plate 6a at the end of the locking shaft 6 is hinged. The guide rod 5a provides guidance and support for the hollow hydraulic jack. As the moving end of the hollow hydraulic jack extends and abuts against the limit nut 5c, it pulls the guide rod 5a and the locking shaft 6, completing the withdrawal of the gate locking shaft.

[0032] Preferably, the axis of the hollow hydraulic jack coincides with the axis of the locking shaft 6, so that the force output by the hollow hydraulic jack is output along the axis of the locking shaft 6, making it easier for the hydraulic cylinder to push or pull the locking shaft 6.

[0033] To facilitate the transfer and installation of the hydraulic tools of this application, in this embodiment, the crossbeam 1a and the support arm 1b are detachably connected.
