[0002] Gas inspection is a key task to ensure the safety of line transmission. As an important component of the gas pipeline system, the valve well contains valves and other related equipment that control the flow of gas, and is usually inspected once a month.

[0003] During inspections, patrolmen typically use a hook-type device to open the manhole cover. However, gas valve manhole covers are often different from other hinged manhole covers and can be opened by a single person using a hook to pull diagonally. These covers are usually made of concrete and have dual inspection holes. To open them, they need to be pulled upward. This makes it difficult for a single person to open and restore the manhole cover; even with two people, the operation is extremely time-consuming and labor-intensive, and is detrimental to work safety.

[0007] Travel wheels are provided at the bent position of the frame;

[0008] A manhole cover lifting member is provided in front of the short frame, and the manhole cover lifting member includes an assembly rod, and two assembly sets are provided on the assembly rod;

[0009] Draw hooks are respectively arranged under the two assembly sleeves.

[0010] The effect achieved in this way is that the hook parts are placed into the detection holes of the manhole cover, and the long frame part of the frame is pressed down to pull the manhole cover upward to detach from the wellhead; the frame part is pushed to move the manhole cover to the side of the wellhead.

[0011] The beneficial effects of the present invention are as follows: the present invention solves the problem of inconvenient opening of the gas valve well in the prior art, and realizes labor-saving opening of the valve well; in particular, the valve well opening can be achieved by a single person, and the opening, restoration and transportation of the valve well are safer.

[0020] Reference Figure 1 、 Figure 2 and Figure 3 The gas valve well opening device of the utility model comprises a frame 1, running wheels 2 and a well cover lifting member 3;

[0021] The frame 1 is an integrated structure, comprising a short frame 11 and a long frame 12. The long frame 12 is bent relative to the short frame 11, and the bending angle is an obtuse angle. The long frame 12 is longer than the short frame 11.

[0022] A traveling wheel 2 is provided at the bending position of the frame 1;

[0023] A manhole cover lifting member 3 is provided in front of the short frame 11. The manhole cover lifting member 3 includes an assembly rod 32. Two assembly sets 33 are provided on the assembly rod 32.

[0024] A draw hook 35 is provided under each of the two assembly sleeves 33 .

[0025] Preferably, the bending angle between the long frame 12 and the short frame 11 is between 110° and 150°.

[0026] The effect achieved in this way is that the hook 35 parts are respectively placed into the detection holes of the manhole cover, and the long frame 12 part of the frame 1 is pressed down to pull the manhole cover upward to detach from the wellhead; the manhole cover can be moved to one side of the wellhead by pushing the frame 1 part.

[0027] In Example 1, the frame 1 is in the form of a circular tube, that is, the long frame 12 and the short frame 11 are connected as a whole and have a bent tube form, and the tube length of the long frame 12 is greater than the tube length of the short frame 11.

[0028] The effect achieved thereby is that the frame 1 itself is lightweight and the assembly cost is lower; and the long frame 12 serves as the downward pressing part, and its length is greater than the short rod to form a labor-saving lever structure, which is convenient for saving effort when lifting the manhole cover.

[0029] Further, refer to the accompanying drawings Figure 1 or Figure 3 , a sleeve 14 is slidably provided on the long frame 12, that is, the sleeve 14 and the long frame 12 are a tube-in-tube structure;

[0030] A position locking member is provided between the sleeve 14 and the long frame 12 .

[0031] Preferably, the position locking member is a spring pin, and correspondingly, positioning holes are provided on the long frame 12 and the sleeve 14 .

[0032] Furthermore, a holding arm is provided at the end of the sleeve 14 , and the holding arm is provided in a direction perpendicular to the sleeve 14 .

[0033] The effect achieved by this is that it is easy to hold with both hands.

[0034] Example 2, refer to the accompanying drawings Figure 3 The bending position of the frame 1 is integrally connected to a walking wheel assembly base at its lower part, and walking wheels 2 are respectively provided on both sides of the walking wheel assembly base.

[0035] The effect achieved in this way is to ensure the overall walking stability of the equipment.

[0036] In embodiment 3, a rotating sleeve 31 is provided in front of the short frame 11 , and an assembly rod 32 is rotatably provided in the rotating sleeve 31 ; the assembly sleeve 33 is fixedly provided on the assembly rod 32 .

[0037] Furthermore, an assembly ring groove is centrally provided on the assembly rod 32 , and the rotating sleeve 31 is sleeved on the assembly ring groove.

[0038] The effect achieved thereby is that the assembly rod 32 can maintain a stable rotation stroke in the rotating sleeve 31 , and based on the rotation of the assembly rod 32 , the direction of lifting the manhole cover can always be kept vertically upward.

[0039] In embodiment 4, the assembly rod 32 is fixedly arranged in front of the short frame 11;

[0040] The assembly sleeve 33 is rotatably arranged on the assembly rod 32 , and the assembly sleeve 33 is slidably arranged on the assembly rod 32 .

[0041] The effect achieved in this way is that, based on the sliding connection between the assembly sleeve 33 and the assembly rod 32, the two assembly sleeves 33 can be adjusted in spacing by sliding, thereby adapting to different detection hole pitches;

[0042] Furthermore, based on the rotational connection between the assembly sleeve 33 and the assembly rod 32, the lifting direction of the manhole cover can always be kept vertically upward.

[0043] In Example 5, a sliding sleeve 34 is provided under the assembly sleeve 33 , one end of the draw hook 35 is passed through the sliding sleeve 34 , and a position locking member is provided between the draw hook 35 and the sliding sleeve 34 .

[0044] Preferably, the position locking member is a hard limit bolt.

[0045] Preferably, when in use, the hook bodies of the two retractor hooks 35 face toward each other.

[0046] The effect achieved thereby is to facilitate adjustment of the exposed length of the drag hook 35 and ensure that the hook bodies of the two drag hooks 35 can be arranged in opposite directions when in use.

[0047] Furthermore, the inner cavity of the sliding sleeve 34 is a spline groove, and the rod body of the retractor 35 is a spline rod corresponding to the spline groove.

[0048] The effect achieved thereby is to quickly position the hook body of the draw hook 35 .

[0049] In Example 6, a reinforcing rib 13 is further provided between the long frame 12 and the short frame 11 .

[0050] In Example 7, the pull hook may also be a chain with a hook body provided at the bottom thereof to fix the manhole cover.

[0051] When the present invention is in use, the hook 35 is respectively placed into the detection hole of the manhole cover. The placement method is similar to that of the existing hook 35. That is, the hook 35 of the present invention can be rotated and adjusted so that the hook body is extended along the length of the detection hole and rotated after being extended so that the bottom surface of the manhole cover cooperates with the hook body to form a limit block. Alternatively, the hook 35 can be inserted and then assembled with the sliding sleeve 34.

[0052] By pressing down the long frame 12 of the frame 1, the manhole cover can be pulled upward to be away from the wellhead; by pushing the frame 1 part, the manhole cover can be moved to one side of the wellhead.

[0053] When restoring, push the manhole cover to the wellhead, and after lowering, partially separate the hook 35 from the manhole cover.
