When the slider is found to slide down accidentally, the emergency stop button can be pressed immediately, the piston rod of the oil cylinder is pushed out, and the elastic telescopic mechanism drives the rotating frame to rotate. Then the ratchet on the rotating frame can engage with a tooth of the rack to stop the slider from sliding down. However, this structure requires manual operation to stop the slider when it moves down, which is easy to cause safety accidents due to untimely operation. Therefore, technical personnel in this field provide a hydraulic press slider anti-slip device to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When implementing: Figure 1-5 As shown, a hydraulic press slide anti-slip device comprises: a connecting block 1 and a mounting seat 102, one side of the connecting block 1 is provided with uniformly distributed anti-slip grooves 101; an anti-slip mechanism 2; wherein the anti-slip mechanism 2 comprises an anti-slip component 21 arranged on the top of the mounting seat 102; the anti-slip component 21 comprises a hydraulic push rod 2102 arranged on the top of the mounting seat 102, the output shaft of the hydraulic push rod 2102 is fixedly connected to the mounting block 2101, and the bottom of the mounting block 2101 is fixedly connected to the inner side of the mounting seat 102. The anti-skid mechanism 2 further comprises a slide block 2107 connected to the wall of the mounting seat 102, a baffle 2108 is slidably connected to the inside of the mounting seat 102, a connecting rod 2103 is fixedly connected to one side of the baffle 2108, the other end of the connecting rod 2103 passes through the mounting block 2101 and is fixedly connected to a baffle 2104 located inside the anti-skid groove 101, and a first spring 2109 is fixedly connected between the other side of the baffle 2108 and the inner wall of the mounting block 2101; the anti-skid mechanism 2 also includes a prompt component 22 arranged inside the mounting seat 102;

[0024] The connecting block 1 is used to connect with the slider of the hydraulic press. The inner wall of one side of the anti-skid groove 101 is set in an inclined surface. Under normal circumstances, the stopper 2104 is located at the inner wall of the anti-skid groove 101, so that the top of the stopper 2104 can block the connecting block 1 against the anti-skid groove 101, thereby ensuring the effect of preventing the slider from sliding down during use. When the hydraulic press slider needs to move up, the inclined inner wall of the anti-skid groove 101 can squeeze the stopper 2104 to drive the connecting rod 2103 to retract to the inside of the mounting block 2101, and at the same time, it can drive the baffle 2108 to compress the first spring 2109 until the next anti-skid groove 101 moves to the stopper 2104. It can be reset under the action of the first spring 2109 to block the anti-skid groove 101, avoiding the situation in which the traditional structure needs to actively retract the stopper 2104 when the slider position is moved up and reset it after the adjustment is completed. The operation is simple and there is no need for the staff to actively use the stopper 2104 to make an emergency stop during the sliding process, which saves time and avoids safety accidents caused by the staff's failure to stop in time.

[0025] like Figure 2 , Figure 3 and Figure 5 As shown, the inner wall of the mounting block 2101 is fixedly connected with a retaining ring 2110 located on the side of the retaining plate 2108 away from the first spring 2109, the inner diameter of the retaining ring 2110 is larger than the diameter of the connecting rod 2103, and the connecting rod 2103 passes through the retaining ring 2110, the inner wall of the stopper 2104 is slidably connected with a trigger plate 2111, the top of the trigger plate 2111 is fixedly connected with a sliding rod 2113, the upper end of the sliding rod 2113 passes through the stopper 2104 and is fixedly connected with a pressure plate 2115 in contact with the inner wall of the anti-skid groove 101, the top of the trigger plate 2111 is fixedly connected with a second spring 2114, the interior of the stopper 2104 is fixedly connected with a pressure sensor 2112 located below the trigger plate 2111, and the anti-skid component 21 also includes a controller 2105 arranged on one side of the mounting seat 102, and a sound and light alarm 2106 is arranged on one side of the controller 2105;

[0026] When the slider slides down, it can drive the connecting block 1 to move down synchronously, thereby applying pressure to the trigger plate 2111 through the anti-slip groove 101, so that it drives the slide bar 2113 to move down and stretch the second spring 2114, and at the same time applies pressure to the pressure sensor 2112. After the pressure sensor 2112 detects that the pressure is greater than the preset value, it transmits a signal to the controller 2105, and the controller 2105 activates the sound and light alarm 2106 to remind the staff that the slider has slipped down;

[0027] When the slider needs to be moved downward, the hydraulic push rod 2102 is started to drive the mounting block 2101 away from the connecting block 1, which can drive the retaining ring 2110 to push the baffle 2108 to separate the retaining block 2104 from the anti-slip groove 101, thereby releasing the limit on the downward movement of the connecting block 1.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, the prompt component 22 includes a threaded sleeve 2204 rotatably connected to the inner wall of the mounting seat 102, a gear 2202 is fixedly connected to the surface of the threaded sleeve 2204, a rack 2201 is meshedly connected to the surface of the gear 2202, one side of the rack 2201 is fixedly connected to the surface of an adjacent sliding block 2107, a threaded rod 2207 is threadedly connected to the inner wall of the threaded sleeve 2204, the lower end of the threaded rod 2207 passes through the threaded sleeve 2204 and is fixedly connected to two guide blocks 2205, the guide blocks 2205 are slidably connected to the inner wall of the mounting seat 102, a sleeve 2203 is fixedly connected to the top of the mounting seat 102, the upper end of the threaded rod 2207 passes through the mounting seat 102 and is fixedly connected to an indicating block 2206 located inside the sleeve 2203;

[0029] In the process of driving the stop block 2104 to separate from the anti-slip groove 101, the rack 2201 can be driven to move synchronously, thereby driving the gear 2202 to rotate. Under the limiting guiding action of the guide block 2205, the gear 2202 can drive the threaded rod 2207 to move upward during rotation and push the indicator block 2206 out of the sleeve 2203. When the stop block 2104 is adjusted to reset, the indicator block 2206 can be retracted into the sleeve 2203. By observing whether the indicator block 2206 is retracted into the sleeve 2203, it is possible to understand whether the stop block 2104 has moved into place.

[0030] When the utility model is in use, the connecting block 1 is used to connect with the slider of the hydraulic press. Under normal conditions, the stopper 2104 is located on the inner wall of the anti-skid groove 101 to prevent the connecting block 1 from sliding down. When the slider of the hydraulic press moves up, the inclined inner wall of the anti-skid groove 101 can squeeze the stopper 2104 to drive the connecting rod 2103 to shrink to the inside of the mounting block 2101 without affecting the normal upward movement of the slider. Until the next anti-skid groove 101 moves to the stopper 2104, it can be reset to block the anti-skid groove 101 under the action of the first spring 2109, avoiding the need for the stopper 2104 to be actively retracted and adjusted when the slider position is moved up in the traditional structure. The operation is simple and there is no need for the staff to actively use the block 2104 to make an emergency stop during the sliding process, which saves time and avoids safety accidents caused by the staff's failure to make an emergency stop in time. At the same time, when the slider slides down, pressure can be applied to the pressure sensor 2112. After the pressure sensor 2112 detects that the pressure is greater than the preset value, it transmits a signal to the controller 2105. The controller 2105 activates the sound and light alarm 2106 to remind the staff that the slider has slipped down. The prompt component 22 can act on the observation to see whether the block 2104 has moved into place, thereby ensuring a good limiting effect of the block 2104.

[0031] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
