Description

Technical Field

[0001] The invention belongs to the technical field of shallow geothermal energy development and utilization, and particularly relates to a drilling rig drill rod quick docking and loading and unloading device Background Art

[0002] Shallow geothermal refers to geothermal resources with a nearly constant temperature within a depth of 200m under the combined effect of solar radiation and geothermal heat flow formed by deep earth heat. At present, the depth of shallow geothermal buried pipe heat exchange holes generally does not exceed 200m, and the installation and removal operations of drill rods for some existing small drilling rigs for underground drilling are still at the stage of manually tightening and loosening them bit by bit with an open-end wrench.

[0003] The prior art lacks devices for loading and unloading such drill rods. To complete the loading and unloading of drill rods, three operators are usually required to cooperate with each other to complete the docking, installation and disassembly of the drill rods. The degree of mechanization is low, the labor intensity of the operators is high, the docking rate of the drill rods is slow, and the loading and unloading takes a long time. In addition, during the loading and unloading process of the drill rods, the drill rods are prone to rotation, slippage, and falling, causing mechanical injuries to the operators, and the operators are prone to rheumatism and other health injuries due to long-term water accumulation or mud spraying in the drill rods. Summary of the invention

[0004] The purpose of the present invention is to provide a drilling rig drill rod quick docking and loading and unloading device to solve the problems of low loading and unloading efficiency, high labor cost and high work risk in the prior art due to the lack of drill rod loading and unloading devices for small drilling rigs.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions to achieve the above problems:

[0006] A drilling rig drill pipe quick docking and loading and unloading device comprises a handrail turntable, which is an annular structure with an open gap, and two mutually parallel first connecting rods are respectively connected to the gap; the other ends of the two first connecting rods are connected to corresponding positions on the inner wall of the handrail turntable, and the distances between the two first connecting rods and the central axis of the handrail turntable are equal.

[0007] The middle parts of the sides away from each other of the two first connecting rods are connected to the inner wall of the handrail turntable through the second connecting rod; the first connecting rod and the second connecting rod are perpendicular to each other; a limiting rod is also connected between the two first connecting rods; the space formed by all the first connecting rods, the second connecting rods and the limiting rod can accommodate the drill rod.

[0008] A plurality of support rods are evenly distributed along the circumferential direction on the lower wall of the handrail turntable, and the lower ends of all the support rods are close to the central axis of the handrail turntable; and the inclination angles of all the support rods are consistent.

[0009] The lower ends of the plurality of support rods are fixedly connected to the jaws of a spanner; the opening direction of the jaws of a spanner is opposite to the notch direction of the handrail turntable; a force lever is hingedly connected to the end of the jaws of a spanner opposite to the opening, and the force lever can enter the notch of the handrail turntable by rotating.

[0010] The utility model also has the following features:

[0011] Furthermore, a reinforcing plate is provided at the opening of the jaws of the wrench.

[0012] Furthermore, the angle between the plurality of support rods and the horizontal plane is 60°.

[0013] Furthermore, the handrail turntable is formed by bending a seamless thin steel pipe.

[0014] Furthermore, the lower wall of the handrail turntable is evenly connected to a plurality of support rods equal in number to the fixed barrier rods through a plurality of fixed barrier rods;

[0015] All fixed stoppers are perpendicular to the plane where the armrest turntable is located.

[0016] Furthermore, a circle of waterproof protective plates is arranged outside all the fixed baffles.

[0017] Furthermore, a hook is connected to one end of the force lever away from the jaws of the wrench.

[0018] Furthermore, the number of support rods is 3.

[0019] Compared with the prior art, the present invention has the following technical effects:

[0020] (I) The drilling rig drill rod quick docking and loading and unloading device of the utility model has structural improvements. In the initial stage of loading and unloading, when a large torque is required, two operators use a force lever and a handrail turntable to perform the drill rod assembly and disassembly operation; in the middle stage of loading and unloading, the torque required is relatively small, the force lever is retracted, and only one operator is required to use the handrail turntable to twist the drill rod. This setting not only improves the loading and unloading efficiency of small drilling rig drill rods, but also saves labor costs, and improves the safety of operations compared with the existing technology that uses only manual loading and unloading.

[0021] (II) The drilling rig drill pipe quick docking and loading and unloading device of the utility model is additionally provided with a circle of waterproof baffle plates on the outside of the fixed baffle rod, so that the operators are protected from water accumulation or mud spraying in the drill pipe during operation, thereby improving the construction working environment and the occupational health management level of the operators, and is suitable for large-scale use and promotion in industry.

[0028] It should be noted that, unless otherwise specified, all components in the present invention are components known in the prior art. For example, the handrail turntable is a known and commonly used handrail turntable.

[0029] The following are specific embodiments of the present invention. It should be noted that the present invention is not limited to the following specific embodiments, and all equivalent changes made on the basis of the technical solution of the present application fall within the protection scope of the present invention.

[0030] like Figure 1 and Figure 2 As shown, a drilling rig drill pipe quick docking and loading and unloading device includes a handrail turntable 1, which is an annular structure with an open gap, and two mutually parallel first connecting rods 2 are respectively connected to the gap; the other ends of the two first connecting rods 2 are connected to the inner wall of the handrail turntable 1, and the distances between the two first connecting rods 2 and the central axis of the handrail turntable 1 are equal.

[0031] The middle parts of the two first connecting rods 2 on the side away from each other are connected to the inner wall of the handrail turntable 1 through the second connecting rod 3; the first connecting rod 2 and the corresponding second connecting rod 3 are perpendicular to each other; a limiting rod 4 is also connected between the two first connecting rods 2; the space formed by all the first connecting rods 2, the second connecting rods 3 and the limiting rod 4 serves as a drill rod positioning cavity, and the distance between the limiting rod 4 and the central axis of the handrail turntable 1 matches the radius of the drill rod of the drilling rig;

[0032] A plurality of support rods 5 are evenly connected to the lower wall of the handrail turntable 1, and the lower ends of all the support rods 5 are close to the central axis of the handrail turntable 1; and the angles between all the support rods 5 and the horizontal plane are consistent;

[0033] like Figure 3 and 4As shown, the lower ends of the plurality of support rods 5 are fixedly connected to the jaws wrench 6; the opening direction of the jaws wrench 6 is opposite to the notch direction of the armrest turntable 1; a force lever 7 is hinged on the jaws wrench 6, and the force lever 7 can enter the notch of the armrest turntable 1 by rotating.

[0034] When in use, the device is inserted from above the drill rod of the drilling rig; the drill rod is allowed to enter the drill rod positioning cavity, and at the same time, the opening of the thumb wrench 6 is tightly fastened to the drill rod.

[0035] The boosting lever 7 is hinged to the jaws wrench 6 through a high-strength hinge. When the drill rod is initially disassembled or is about to be tightened, a larger torque is required. The folded boosting lever 7 is opened and placed horizontally, and a force is applied. Two operators use the boosting lever and the handrail turntable to disassemble and assemble the drill rod.

[0036] When the drill rod is connected and ready to be installed or loosened, the booster lever 7 is folded and retracted, and the handrail turntable 1 is rotated quickly and continuously. At this time, only one operator is required to use the handrail turntable to turn the drill rod. This setting not only improves the loading and unloading efficiency of the drill rod of the small drilling rig, but also saves labor costs, and improves the safety of the operation compared with the existing technology that uses only manual loading and unloading.

[0037] Specifically, the angle between the plurality of support rods 5 and the horizontal plane is 60°.

[0038] Specifically, the number of the support rods 5 is 3.

[0039] As a preferred solution, a reinforcing plate 8 is provided at the opening of the jaws wrench 6. This arrangement is convenient for increasing the contact area between the jaws wrench 6 and the drill rod lock joint during the process of loading and unloading the drill rod, and ensuring that the contact surface is balanced and fully stressed.

[0040] As a preferred solution, the handrail turntable 1 is formed by bending a seamless thin steel pipe to ensure that its strength meets the requirements.

[0041] Furthermore, the lower wall of the armrest turntable 1 is evenly connected to a plurality of support rods 5 whose number is equal to the fixed baffle rods 9 through a plurality of fixed baffle rods 9 .

[0042] All the fixed blocking rods 9 are perpendicular to the plane where the handrail rotating disk 1 is located.

[0043] As a preferred solution, a circle of waterproof protective plates 10 are arranged outside all fixed baffles 9. According to conventional selection, the waterproof protective plates 10 are made of transparent polyvinyl chloride material and are closely attached to the fixed baffles 9 for plastic tie punching and binding. This protects the operators from water accumulation or mud spraying in the drill pipe, improves the construction working environment, and improves the occupational health management level of the operators.

[0044] As a preferred solution, one end of the force lever 7 away from the jaws of the wrench 6 is connected with a hook 11. When the device is not in use, it is convenient to store.
