DETAILED DESCRIPTION

[0029] In order to more clearly illustrate the implementation of the utility model or the technical solution in the prior art, the drawings required for the implementation are briefly introduced below. Obviously, the drawings described below are only some implementations of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. The implementation methods cannot be described one by one here, but the implementation methods of the present invention are not therefore limited to the following implementation methods.

[0031] It should be pointed out that the front end, front side and front part mentioned in the following embodiment are all the forward direction of the drilling, anchoring and protecting machine, and the rear is relative to the forward direction. Similarly, up, down, left and right are all referred to the forward direction of the drilling, anchoring and protecting machine, which will not be repeated below.

[0032] Embodiment: A hydraulically controlled drill pipe box device for oil drill pipe delivery, recovery and transportation, the structure of which is as follows Figure 1-Figure 3 As shown, it includes an outer frame 1, an inner frame 2, a telescopic hydraulic cylinder 3, a wire rope 4, a pulley guide device, a control valve group 8 and an electronic control device 9;

[0033] Reference Figure 4-Figure 7As shown, the inner frame 2 is placed inside the outer frame 1, used to store the drill rod 22, and mainly includes an inner frame body 10, a guide pulley 11, a drill rod stopper 12 and a drill rod stand 13; wherein the inner frame body 10 is welded into a frame structure by section steel, the drill rod stopper 12 is inside the inner frame 2, and the inner part of the inner frame 2 is divided into several layers in the vertical direction, and the drill rod 22 is stored in layers; the drill rod stand 13 is located at the top of the inner frame body 10. The guide pulley 11 is arranged around the inner frame 2, and the four inner frame guide rails 20 of the outer frame 1 realize the guidance and limit of the inner frame 2.

[0034] The spacing between the drill rod stopper bars 12 can be adjusted to suit drill rods of different diameters. Specifically, the stopper bar root is fixed by a fixing pin 17, and the adjustment spring 14 is fixed to the lower front part of the stopper bar root by a fixing nut 15 and a guide rod 16. The spacing of the stopper bars is adjusted by retracting the spring, and then the adjusted drill rod stopper bars 12 are fixed by the fixing pin 17.

[0035] Reference Figure 8-Figure 10 As shown, the outer frame 1 is used to support the load of the entire device and the drill rod, including an outer frame body 18, a skid structure 19 and an inner frame guide rail 20. The outer frame body 18 is welded by steel sections and is used to bear the weight of the inner frame 2 and the drill rod 22. The connecting ear plate 21 is used to connect adjacent drill rod box devices, position each drill rod box device as an independent module, and combine several hydraulically controlled drill rod box devices into a system; the skid structure 19 is used for the transportation of the drill rod device, and can quickly complete the loading, transportation and disassembly of the drill rod box and the drill rod 22.

[0036] In this embodiment, the inner frame 2 is lifted and lowered by the telescopic hydraulic cylinder 3 , the steel wire rope 4 and the pulley guide device; wherein the pulley guide device includes a top pulley 5 and a bottom pulley 6 .

[0037] Specifically, there are four telescopic hydraulic cylinders 3, which are arranged in groups of two on the side beams on both sides of the outer frame 1, and the piston rod of each group of telescopic hydraulic cylinders 3 faces outward; the telescopic amount of each group of telescopic hydraulic cylinders 3 is kept synchronous, and each group is equipped with a wire rope adjuster 7 for adjusting the length of each group of wire ropes; one end of the wire rope 4 is connected to the piston rod of the telescopic hydraulic cylinder 3, and the wire rope is guided from the horizontal direction to the vertical upward direction through the guide pulley 6, and then the wire rope is guided vertically downward through the guide pulley 5 and connected to the ear plate at the lower part of the inner frame.

[0038] Through the extension and retraction of each group of telescopic hydraulic cylinders 3 on both sides, the steel wire rope 4 is driven to lift the inner frame 2 to the corresponding height. By controlling the different extension and retraction amounts of each group of telescopic hydraulic cylinders 3 on both sides, the predetermined lifting height and tilt angle of the inner frame 2 are achieved, and the drill rod 22 is rolled out or recovered under its own weight; the synchronous extension and retraction of each group of telescopic hydraulic cylinders 3 is achieved through the control valve group 8, and the electric control device 9 here can be an electric control box to realize the control of the control valve group 8, converting the hydraulic control into circuit control, and as an electric control module, it is convenient for multiple modules to perform local centralized control or remote wired / wireless control. In specific operations, the electric control device 9 can be controlled by a wireless control device, thereby realizing remote control of the entire device.

[0039] Reference Figure 11-13 As shown, during specific use, each hydraulically controlled drill rod box device can be used as a transport and working module. A corresponding number of hydraulically controlled drill rod box devices are placed on both sides of the automatic hydraulic rod rack 23. Adjacent hydraulically controlled drill rod box devices are connected by connecting ear plates 21. The inner frame 2 of each hydraulically controlled drill rod box device is filled with drill rods 22. In this example, the inner frame 2 is divided into four layers, and each layer stores 11 drill rods 22. If the drill rod 22 is to be transported from the outermost side to the automatic hydraulic rod rack 23, firstly control the telescopic hydraulic cylinder 3 to raise the inner frame 2 and tilt it at a certain angle toward the power catwalk 24. The first layer of drill rods rolls under its own weight to the drill rod platform 13 on the top of the adjacent hydraulically controlled drill rod box device. The adjacent hydraulically controlled drill rod box device tilts the drill rods in the same way and transports them to the top of the hydraulically controlled drill rod box device on the closer side. According to the above principle, the drill rods 22 can be gradually transported to the automatic hydraulic rod rack 23, thus completing the transportation of the drill rods 22. Similarly, by controlling the telescopic amount of the telescopic hydraulic cylinder 3, all the drill rods 22 in the hydraulically controlled drill rod box device can be transported to the automatic hydraulic rod rack 23 in turn. For details, refer to Fig.12 Step01-step06.

[0040] If the drill rod 22 is to be recovered into the hydraulically controlled drill rod box device, the drill rod 22 can be recovered and stored by following the reverse operation steps of the drill rod delivery. Fig.13 Step 21-step 25.

[0041] After all the drill rods 22 are recovered, the adjacent hydraulically controlled drill rod box devices can be used as independent transport modules after the connecting pins are removed to achieve rapid transport of the drill rods.
