Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic wrench anti-pinch manual installation, in particular to a hydraulic wrench anti-pinch manual installation. Background Art

[0002] A hydraulic wrench is a high-strength tool that uses hydraulic torque to tighten or loosen bolts and nuts. It is an efficient, safe and reliable bolt connection tool that is widely used in various industrial fields. During the operation of the hydraulic wrench, the part that contacts the bolt or nut is easy to clamp the operator's hand. This is because the hydraulic wrench transmits the hydraulic torque to the bolt or nut through the reaction arm, causing it to rotate. In this process, if the operator's hand accidentally touches the area where the reaction arm contacts the bolt or nut, it may be clamped, so an anti-pinch manual device is needed to assist the operation.

[0003] A hydraulic wrench anti-pinch manual device disclosed in the authorization announcement number CN219806023U, although the utility model is used to control the start and stop of the hydraulic station through the control switch, the base is set on the mounting part of the reaction arm, and the operator holds the handle and controls the start and stop of the hydraulic station through the control switch. The hydraulic wrench is stabilized by holding the handle, and the base is set on the reaction arm to provide a stable and reliable fulcrum for the reaction arm, avoiding safety accidents caused by placing hands on the reaction arm, and the safety is higher; one operator can operate the hydraulic wrench and the hydraulic station at the same time, which is more efficient than two operators operating the hydraulic wrench and the hydraulic station control handle separately.

[0004] However, the manual anti-pinch installation of the hydraulic wrench has the following disadvantages: the size of the arc base is fixed, and it is difficult to adapt to the reaction arms of hydraulic wrenches of different sizes; when the reaction arm is small, there may be a gap between the base and the reaction arm, which is relatively unstable when used; and the base is fixed to the main body, and the cost of replacement is high.

[0030] Reference Figure 1-5 , which is the first embodiment of the utility model, provides a hydraulic wrench anti-pinch manual device, the structure includes:

[0031] The hydraulic wrench body 100 includes a reaction arm 101, which is detachably connected to the hydraulic wrench body 100, and the hydraulic torque is transmitted to the bolt or nut through the reaction arm 101, so as to realize the bolt connection in cooperation with the hydraulic wrench body 100;

[0032] The tooling assembly 200 includes a tooling body 201, which is C-shaped. An A-shaped arc plate 202 is fixedly connected to one side of the inner wall of the tooling body 201, and a telescopic rod 203 is fixedly connected to the other side of the inner wall of the tooling body 201. One end of the telescopic rod 203 is fixedly connected to a B-shaped arc plate 204. The tooling assembly 200 and the hydraulic wrench body 100 cooperate to prevent the hand from being pinched. The tooling body 201 is fixed on the reaction arm 101 by clamping the A-shaped arc plate 202 and the B-shaped arc plate 204. The telescopic rod 203 limits the B-shaped arc plate 204 to make its movement more stable.

[0033] The control component 300 includes a fixed block 301, which is fixedly connected to the surface of the B arc plate 204. A connecting rod 302 is fixedly connected to the fixed block 301. A spring 303 is sleeved on the surface of the connecting rod 302. A clamping block 304 is fixedly connected to the surface of the connecting rod 302. The position of the B arc plate 204 is controlled by the control component 300. The connecting rod 302 is pulled outward slightly to stretch the spring 303. At this time, the clamping block 304 is disengaged from the slot and can slide in the slide slot, thereby driving the B arc plate 204 to move. The connecting rod 302 is released and the spring 303 rebounds without force, causing the clamping block 304 to enter the slot and be fixed. The reaction arm 101 is clamped by the cooperation of the B arc plate 204 and the A arc plate 202.

[0034] Furthermore, a through groove is provided on the tool body 201, and the connecting rod 302 runs transversely through the through groove. The connecting rod 302 passes through the through groove to connect to the B arc plate 204, which is convenient for operation.

[0035] Furthermore, a slide groove is provided at the top of the through groove, and a card slot is provided on the inner wall of the slide groove. The card block 304 is movably connected to the card slot. When the card block 304 is inserted into the card slot, the position of the B arc plate 204 is fixed. When the card block 304 is out of the card slot, it can slide in the slide groove, thereby adjusting the position of the B arc plate 204.

[0036] Furthermore, one end of the spring 303 is fixedly connected to the inner wall of the through slot, and the other end of the spring 303 is fixedly connected to the connecting rod 302. The elasticity of the spring 303 itself can drive the block 304 to rebound when no force is applied.

[0037] Furthermore, an installation groove is opened on the inner wall of one side of the tooling body 201, and a sensor 2011 is fixedly installed inside the installation groove. An alarm 2012 is fixedly installed on the surface of one side of the tooling body 201. The alarm 2012 and the sensor 2011 are electrically connected. When the worker puts his hand on the hydraulic wrench body 100, the sensor 2011 can sense the approach of the human body, and an alarm is sounded through the alarm 2012 to remind the worker to be careful not to pinch his hand.

[0038] Furthermore, a handle 2013 is fixedly connected to the surface of the tool body 201, and an anti-skid sticker is attached to the handle 2013. The handle 2013 can facilitate the operation of the staff, and the provision of the anti-skid sticker can prevent the staff from slipping due to excessive sweat on their hands.

[0039] When the operator puts his hand on the hydraulic wrench body 100, the sensor 2011 can sense the human body approaching, and the alarm 2012 can sound an alarm, thereby reminding the operator to be careful of pinching his hand.

[0040] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
