All other embodiments, which are derived by a person skilled in the art based on the embodiments of the utility model, fall within the scope of protection of the utility model.

Embodiments of the utility model:

as shown in fig. 1-5, a vertical shaft equipment gap measuring device comprises a fixing frame 3, a telescopic rod 1 and a roller assembly, wherein the fixing frame 3 comprises a bottom plate, a first fixing plate 31 and a second fixing plate 32, and the first fixing plate 31 and the second fixing plate 32 are arranged at parallel intervals and are fixed on the bottom plate. The centers of the first fixing plate 31 and the second fixing plate 32 are respectively provided with a through hole, so that the telescopic rod 1 passes through the first fixing plate 31 and the second fixing plate 32, and in a normal state, two ends of the telescopic rod 1 extend out. The telescopic rod 1 is sleeved with a spring 5, and the spring 5 is positioned between the first fixing plate 31 and the second fixing plate 32 for resetting. The outer periphery of the telescopic rod 1 is provided with a stop part, the stop part is positioned at the inner side of the first fixing plate 31, one end of the spring 5 is abutted against the inner side of the second fixing plate 32, and the other end is abutted against the stop part. In this embodiment, the stopper portion is a baffle plate 11, and the baffle plate 11 is an annular plate having an outer diameter larger than that of the telescopic rod 1. Normally, under the action of the spring 5, the baffle 11 is attached to the inner side of the first fixing plate 31; when the telescopic rod 1 receives axial pressure, the telescopic rod 1 moves leftwards to drive the baffle 11 to compress the spring 5, and when the telescopic rod 1 is not stressed any more, the telescopic rod is reset under the action of the spring 5.

The roller assembly comprises a roller frame 21 and a roller 22, wherein the roller frame 21 is fixed at one end (defined as the right end) of the telescopic rod 1, and the roller is rotatably assembled on the roller frame 21. The rollers 22 are adapted to contact the inner wall of the wellbore in rolling engagement.

The telescopic rod 1 is also sleeved with an indicator 6, the indicator 6 is provided with a ring body 62 and an indicator needle 61 arranged on the side edge of the ring body 62, the ring body 62 is sleeved on the telescopic rod 1, the central hole of the indicator 6, namely a through hole of the ring body 62, is larger than the outer ring of the spring 5, and when the spring 5 stretches, the indicator 6 can pass through the middle of the ring body 62, and the spring 5 and the indicator 6 are not interfered with each other.

The indicator 6 has a pushing surface which cooperates with the stop portion (baffle 11) when the telescopic rod 1 is pressed, the pushing surface is formed by the side surface of the ring body 62, and when the telescopic rod 1 is pressed axially, the baffle 11 compresses the spring 5 and pushes the indicator 6 to move. In order to improve stability, a support plate is arranged at the bottom side of the ring body 62, and the support plate is arranged on the bottom plate of the fixing frame 3 and can move along with the ring body 62 to avoid the indicator 6 from toppling over.

The fixed frame 3 is provided with a measuring ruler 4, and the measuring ruler 4 is arranged in parallel with the telescopic rod 1. The zero graduation mark of the measuring scale 4 is located on one side of the first fixing plate 31. The indicator needle 61 is used in conjunction with the measuring scale 4 to indicate the scale on the measuring scale 4.

The measuring ruler 4 adopts the existing steel ruler and is welded on the fixing frame 3.

The fixing frame 3 comprises a first clamping plate 33 and a second clamping plate 34, and bolts are assembled on the first clamping plate 33. When the device is installed and used, the first clamping plate 33 and the second clamping plate 34 are used for clamping the corresponding positions of the skip, and are tightly propped by bolts.

When the measuring device is used, the working principle is as follows:

the fixing frame 3 is arranged on the skip through the clamping plates and the bolts 7, and four fixing frames can be arranged at four corners of the skip respectively. Along with the operation of the skip, the roller in the device can contact with the well wall to roll, and under normal conditions, the indicator needle 61 of the indicator 6 is positioned at the 0 scale of the measuring scale 4, and the indication gap meets the specification. At the position with small passing clearance, the telescopic rod 1 is pressed, the baffle 11 compresses the spring 5 and drives the indicator 6 to move at the same time, so that the indicator needle indicates other scale positions. As the skip continues to run, the telescopic link 1 can return where the clearance is in line with the regulations, the spring 5 returns, but the indicator needle 61 does not return with it. The measurement result is inconvenient to check in the operation process of the skip, after the operation is finished, the gap size condition can be reflected through the indicating needle, and if the indicating needle indicates other scale positions, the gap is smaller, and the skip needs to be adjusted. After one detection period is completed, the indicator 6 is reset manually and moved to the 0 scale.

The measuring device provided by the utility model has the advantages that the structure is simple, the measuring device can automatically detect along with the operation of the skip after being installed, the use is convenient, the overhaul time of an overhaul worker is greatly reduced, and the labor intensity is lightened.
