[0002] Shale gas is an unconventional natural gas that exists in organic-rich mudstone and its interlayers. It mainly exists in adsorption and free states. It is mainly composed of methane. It is a clean and efficient energy resource and chemical raw material. It is mainly used for residential gas, urban heating, power generation, automobile fuel and chemical production, etc. It has a wide range of uses. Shale gas production generally does not require drainage, has a long production cycle of generally 30 to 50 years, has a high success rate in exploration and development, and has high industrial and economic value.

[0003] Before shale gas is officially mined, it is necessary to conduct surveys and sampling, and then analyze the samples in the laboratory to determine the distribution, reserves and geological characteristics of shale gas resources. Since it is not always possible to find a relatively flat ground to place the shale gas exploration sampling equipment during shale gas exploration sampling, the uneven ground during sampling will lead to poor equipment stability during construction, posing certain safety hazards, increasing the difficulty of construction and the probability of accidents.

[0004] Therefore, a shale gas exploration sampling pre-processing device is needed. Utility Model Content

[0005] The purpose of the utility model is to provide a shale gas exploration sampling pre-treatment device, so as to solve the problem that the existing shale gas exploration sampling pre-treatment device encounters uneven ground, which will lead to poor equipment stability during construction, pose certain safety hazards, increase construction difficulty and the probability of accidents. The specific technical solution is as follows:

[0006] A shale gas exploration sampling pre-processing device, comprising a hydraulic cylinder, a motor, a top plate, a bottom plate, a support rod, a lifting plate, a drill bit, a guide rod and a roller, wherein rollers are installed at the bottom corners of the bottom plate, support rods are vertically installed at the top corners of the bottom plate, the top plate is installed together with one end of the support rod away from the bottom plate, a through hole is opened in the middle of the bottom plate, the hydraulic cylinder is installed on the top of the top plate and is located directly above the through hole, the output end of the hydraulic cylinder passes through the top plate, the lifting plate is installed on the output end of the hydraulic cylinder, the motor is installed on the side of the lifting plate away from the hydraulic cylinder, the output end of the motor is installed with a drill bit, guide holes are provided at both ends of the lifting plate, and guide rods matching the guide holes are installed between the top plate and the bottom plate;

[0007] It also includes an electric push rod and a pressure block. A plurality of the electric push rods are vertically installed at the corners of the top plate, and the output ends of the electric push rods are oriented vertically downward. The pressure block is installed on the output ends of the electric push rods.

[0008] Preferably, a buffer unit is also included, which includes a spring, a pre-tightening sleeve, a baffle and a telescopic rod. A movable groove is opened on the output end of the electric push rod, the pre-tightening sleeve is installed in the movable groove through a threaded connection, the telescopic rod is slidably installed in the pre-tightening sleeve, one end of the telescopic rod away from the movable groove is connected to the pressure block, and a baffle is installed at the other end of the telescopic rod, the diameter of the baffle is equal to the outer diameter of the pre-tightening sleeve, the spring is installed in the movable groove, and the two ends of the spring are elastically abutted against the bottom of the movable groove and the baffle respectively.

[0009] Preferably, the telescopic rod and the pressing block are connected by a ball joint.

[0010] Preferably, an anti-skid pad for increasing friction is installed on the side of the pressing block away from the electric push rod.

[0011] Preferably, a folding handle for facilitating the rotation of the preload sleeve is installed at one end of the preload sleeve away from the spring.

[0012] Preferably, it also includes a horizontal adjustment unit, which includes a shell, a cross bar, a screw and a rotating handle. The shell is horizontally installed at the top corner of the top plate, and the long side of the shell is parallel to the long side of the top plate.

[0013] Compared with the existing technology, the utility model has the following beneficial effects:

[0014] 1. The utility model uses an electric push rod in conjunction with a buffer unit. The output end of the electric push rod pushes the telescopic rod to move closer to the ground. When the pressure block contacts the ground, the four pressure blocks form an auxiliary support for the shale gas exploration sampling pre-processing device, thereby avoiding the problem of poor stability of the shale gas exploration sampling pre-processing device when working on uneven ground. If the pressure on the telescopic rod is greater than the deformation force of the spring, the telescopic rod will squeeze the spring to deform, eliminating the need for precise control by the operator, while increasing the friction between the pressure block and the ground, further increasing stability.

[0015] 2. The utility model adjusts the horizontal position of the electric push rod and the pressure block through the horizontal adjustment unit, so that the pressure block can be moved to a more suitable ground for support, increasing the practicality of the shale gas exploration sampling pre-treatment device. At the same time, the utility model connects the pressure block and the telescopic device through a ball joint, so the pressure block can rotate 360 degrees, so that the pressure block can fit the ground as much as possible, increase the contact area with the ground, and further increase the stability of the shale gas exploration sampling pre-treatment device.

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] refer to Figures 1 to 3, rollers 8 are installed at the bottom corners of the bottom plate 4 by bolts, support rods 5 are vertically installed at the top corners of the bottom plate 4 by bolts, and the ends of the support rods 5 away from the bottom plate 4 are commonly installed with the top plate 3 by bolts. A through hole 9 is opened in the middle of the bottom plate 4, the hydraulic cylinder 1 is installed on the top of the top plate 3 by bolts, and is located directly above the through hole 9, the output end of the hydraulic cylinder 1 passes through the top plate 3, the lifting plate 6 is installed on the output end of the hydraulic cylinder 1 by bolts, the motor 2 is installed on the side of the lifting plate 6 away from the hydraulic cylinder 1 by bolts, and a drill bit 23 is installed on the output end of the motor 2, guide holes are provided at both ends of the lifting plate 6, and guide rods 7 matching the guide holes are installed between the top plate 3 and the bottom plate 4 by bolts.

[0024] The top corners of the top plate 3 are horizontally welded with a shell 18, the long side of the shell 18 is parallel to the long side of the top plate 3, the end of the shell 18 away from the hydraulic cylinder 1 is provided with an opening 22, the other end of the shell 18 is provided with a rotating mounting hole, the cross bar 19 is slidably installed in the shell 18, the bottom of the end of the cross bar 19 away from the rotating mounting hole is connected to the electric push rod 10 by bolts, the output end of the electric push rod 10 is facing vertically downward, the other end of the cross bar 19 is provided with a threaded hole, the lead screw 20 is rotatably installed in the rotating mounting hole, and the lead screw 20 and the threaded hole cooperate with each other, and the end of the lead screw 20 away from the cross bar 19 is provided with a rotating handle 21. Rotating the rotating handle 21 can adjust the extension length of the cross bar 19, thereby adjusting the pressure block 11 to move to a more suitable ground for support, thereby increasing the practicality of the shale gas exploration sampling pre-treatment device.

[0025] An active groove 16 is provided on the output end of the electric push rod 10, and the pre-tightening sleeve 13 is installed in the active groove 16 through a threaded connection, and the telescopic rod 15 is slidably installed in the pre-tightening sleeve 13. The end of the telescopic rod 15 away from the activity is connected to the pressure block 11 through a ball joint 17, so the pressure block 11 can rotate 360 degrees, so that the pressure block 11 can fit the ground as closely as possible, increase the contact area with the ground, and further increase the stability of the shale gas exploration sampling pre-treatment device. A baffle 14 is welded to the other end of the telescopic rod 15, and the diameter of the baffle 14 is equal to the outer diameter of the pre-tightening sleeve 13, so the baffle 14 cannot pass through the pre-tightening sleeve 13, and can only be abutted or separated from the pre-tightening sleeve 13. The spring 12 is installed in the active groove 16, and the two ends of the spring 12 are elastically abutted against the bottom of the active groove 16 and the baffle 14 respectively. A folding handle for facilitating the rotation of the pre-tightening sleeve 13 is installed at one end of the pre-tightening sleeve 13 away from the spring 12. The operator can rotate the pre-tightening sleeve 13 through the folding handle to squeeze the spring 12, giving the spring 12 a certain initial deformation force. If the pressure on the telescopic rod 15 is greater than the deformation force of the spring 12, the telescopic rod 15 will squeeze the spring 12 to deform, so that the operator does not need to perform precise control, eliminates the impact force on the electric push rod 10 when the pressure block 11 contacts the ground, and extends the service life of the electric push rod 10. At the same time, the friction between the pressure block 11 and the ground is increased, further increasing stability. An anti-skid pad for increasing friction is installed on the side of the pressure block 11 away from the electric push rod 10, which can further improve the stability of the shale gas exploration sampling pre-treatment device during operation.

[0026] In summary, after the operator moves the shale gas exploration sampling pre-treatment device to the destination, he turns the rotary handle to adjust the horizontal position of the electric push rod 10, and then starts the electric push rod 10 to make the pressure block 11 contact the ground, thereby supporting the entire shale gas exploration sampling pre-treatment device and ensuring the stability of the shale gas exploration sampling pre-treatment device during operation.
