Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, specifically to a tubing reel assembly and an engineering vehicle. Background Technology

[0002] The drilling mechanism or rotary head of the drilling rig needs to be connected to hydraulic hoses. A hose reel system is installed to prevent the hoses from being worn or damaged due to bending and pulling during the operation of the drilling mechanism or rotary head.

[0003] For example, Chinese invention patent with publication number CN115162949A discloses a pneumatic double-acting propeller and a rock drilling rig. In this invention, a hose reel is provided on the rear slide plate. The hose reel is provided with grooves for limiting hoses, so that the hoses are arranged in a single layer and tensioned on the hose reel.

[0004] In the aforementioned prior art, the hose reel on the rear slide plate can only accommodate a single layer of hoses. When the number of hoses is large, the axial dimension of the hose reel becomes large, which is inconvenient for use. Furthermore, when multiple layers of hoses are arranged, all the hoses are squeezed together, which easily leads to tangling and mutual wear during operation. To reduce the risk of wear, grease needs to be applied to the hoses; however, grease easily attracts slag, and the slag trapped within can also cause hose wear. In addition, lubricating grease easily sticks to clothing, causing inconvenience. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide an oil pipe reel assembly and an engineering vehicle.

[0006] The technical solution provided by this utility model is as follows:

[0007] In a first aspect, there is a tubing reel assembly, including a carriage on which at least two reels are mounted for receiving tubing around; all reels are arranged approximately side by side; along the direction of reel arrangement, the radius of each reel decreases sequentially, and the difference between the radii of two adjacent reels is not less than the diameter of the tubing.

[0008] As an optional implementation of the first aspect, a plane perpendicular to the direction of carriage movement is taken as the projection plane; the projections of the axis of the reel on the projection plane are approximately coincident; or, the projections of the axis of the reel on the projection plane are approximately parallel.

[0009] As an optional implementation of the first aspect, the carriage is provided with an outer mounting surface, and the reel is installed obliquely on the outer mounting surface, forming a drill rod clearance space at the end of the reel away from the carriage; a vertical line perpendicular to the outer mounting surface is drawn, and the angle between the axis of the reel and the vertical line is denoted as a, where the value of a ranges from 10° to 45°.

[0010] Optionally, the reel is mounted obliquely on the outer mounting surface via a connecting frame; the connecting frame is provided with a first leg and a second leg that are connected to the outer mounting surface; wherein, the second leg is higher than the first leg, and a clearance space for the transmission mechanism is formed between the connecting frame and the outer mounting surface.

[0011] Furthermore, a sprocket is mounted on the carriage; the sprocket is located approximately in the middle of the carriage; the height of the clearance space for the transmission mechanism is greater than the radius of the sprocket.

[0012] Furthermore, a pair of sprocket supports are detachably mounted on the carriage, and the sprocket is mounted between the pair of sprocket supports; a pressure plate is detachably mounted on the end of the sprocket support away from the carriage; a sprocket guide bar is detachably mounted on the side of the pressure plate facing the sprocket.

[0013] As an optional technical solution in the first aspect, the slide carriage is equipped with symmetrically arranged sliders on the side away from the reel; the sliders are provided with inclined strip holes; the sliders are connected to the slide carriage by bolts passing through the strip holes.

[0014] As one alternative technical solution in the first aspect, the reel is provided with multiple storage slots, which are independent of each other.

[0015] As an optional technical solution in the first aspect, a vertical shaft is installed on the carriage, and the reel is rotatably connected to the vertical shaft.

[0017] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0018] This invention features multiple reels on a carriage, allowing multiple oil pipes to be wound onto different reels. This ensures a single-layer arrangement of the oil pipes on each reel, preventing pipe compression and tangling, and eliminating the need for lubrication. Furthermore, this application arranges the reels side-by-side, with the radii of each reel decreasing sequentially. The difference in radius between two adjacent reels is not less than the diameter of the oil pipe. Oil pipes wound on the same reel are considered a group, and different groups of oil pipes are arranged radially. This reduces the axial dimension of the reels and prevents wear between different groups of oil pipes. Attached Figure Description

[0029] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0030] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed in this utility model. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity and not intended to limit the scope of implementation. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0031] In one embodiment, this application provides a tubing reel assembly, such as... Figure 1 As shown, the tubing reel assembly includes a carriage 201 that can slide along a slide rail, thereby keeping the tubing taut at all times.

[0032] Because there are many oil pipes, and in order to ensure that all oil pipes are arranged in a single layer, multiple reels 101 are installed on the carriage 201 in this embodiment. For example, there are at least two reels 101, as shown in the accompanying drawings of this application, but there could also be three, four, five, etc. Because multiple reels 101 are provided, the oil pipes can be distributed and wound on each reel 101, so that the oil pipes on each reel 101 are arranged in a single layer, and there will be no entanglement between the oil pipes, which can also reduce the use of lubricating grease.

[0033] Furthermore, when multiple reels 101 are set, the axial length of each reel 101 can be controlled within a reasonable range, thereby reducing the inconvenience caused by excessive axial length of the reel 101.

[0034] In this embodiment, the reels 101 are arranged approximately side-by-side, meaning they are arranged in a roughly linear fashion. Along the arrangement direction of the reels 101, the radius of each reel decreases sequentially, and the difference in radius between two adjacent reels is not less than the diameter of the tubing. Therefore, when tubing is wound on two adjacent reels, the tubing on one reel will not come into contact with the tubing wound on the adjacent reel, thus preventing wear on the tubing wound on different reels.

[0035] For example in Figure 1 In this configuration, when two reels 101 are used, the radius of the larger reel is denoted as R2, and the radius of the smaller reel is denoted as R1. The value of R2 minus R1 should be greater than or equal to the diameter of the tubing. Preferably, the value of R2 minus R1 should be greater than or equal to the diameter of the tubing wound on the larger reel. In this case, if... Figure 2 As shown, if the oil pipes wound on the same reel are considered as a group, then the oil pipes of different groups are arranged radially along the reel. At this time, the oil pipes of different groups are arranged in the radial direction of the reel, and there will be no friction between the oil pipes of each group, thereby avoiding wear between the oil pipes of different groups and reducing the use of lubricating grease.

[0036] Regarding the arrangement of multiple reels 101, as an optional implementation scheme, a plane perpendicular to the direction of carriage movement is taken as the projection plane, such as... Figure 1 As shown, the projections of the axis of the reel 101 onto the projection plane roughly coincide, and the reel 101 is arranged vertically (in the direction of carriage movement). As another optional implementation, a plane perpendicular to the direction of carriage movement is taken as the projection plane, and the projections of the axis of the reel 101 onto the projection plane are roughly parallel (not shown in the figure). In this case, the reel 101 is not arranged vertically, but rather inclined in the vertical direction (in the direction of carriage movement).

[0037] When the tubing reel assembly is used in a hydraulic top hammer drilling rig, since the drill rod axis is generally parallel to the direction of movement of the slide 201, while the reel 101 axis is perpendicular to the direction of movement of the slide 201, the reel 101, which has a larger axial length, will interfere with the drill rod.

[0038] To prevent the reel 101 from obstructing or interfering with other mechanisms, in one embodiment, such as Figure 4 As shown, the carriage 201 has an outer mounting surface, and the reel 101 is mounted at an angle on the outer mounting surface. At this time, on the end of the reel 101 away from the carriage 201, a drill rod avoidance space is formed on the inclined side of the reel 101. At this time, when the drill rod is switched, the drill rod will not collide with the reel 101.

[0039] Preferably, such as Figure 3 As shown, draw a vertical line perpendicular to the outer mounting surface. The angle between the axis of reel 101 and the vertical line is denoted as 'a'. The value of 'a' ranges from 10° to 45°, for example, 10°, 12°, 15°, 20°, 25°, 27°, 30°, 34°, 38°, 43°, 45°, etc.

[0040] Regarding the connection method between the reel 101 and the carriage 201, in one optional embodiment, such as... Figure 5 As shown, the reel 101 is obliquely mounted on the outer mounting surface via a connecting bracket. Specifically, the connecting bracket has a first support leg 103-1 and a second support leg 103-2 connected to the outer mounting surface. The second support leg 103-2 is higher than the first support leg 103-1, and is located on the side of the reel 101 away from the drill rod. This not only creates a drill rod clearance space at the end of the reel 101 away from the slide 201, but also a transmission mechanism clearance space between the connecting bracket and the outer mounting surface. Furthermore, the transmission mechanism clearance space and the drill rod clearance space are diagonally distributed, meaning the transmission mechanism clearance space is closer to the middle of the slide 201. In this case, when the transmission mechanism is located in the middle of the slide 201, it not only adapts to the transmission mechanism clearance space but also improves the movement stability of the slide 201.

[0041] For the transmission mechanism, in one embodiment, such as Figures 3-8 As shown, a sprocket 301 is installed on the carriage 201. The sprocket 301 can be adapted to the transmission chain, thereby driving the carriage 201 to move along the slide rail through the chain and sprocket.

[0042] To improve stability, sprocket 301 is located approximately in the middle of carriage 201. Furthermore, to prevent interference between the chain sprocket and reel 101, the clearance space of the transmission mechanism is made greater than the radius of sprocket 301.

[0043] like Figure 6 , 8 As shown, a pair of sprocket supports 302 are detachably mounted on the carriage 201, with the sprocket 301 mounted between the two sprocket supports 302. A pressure plate 303 is detachably mounted on the end of the sprocket support 302 facing away from the carriage 201, and a sprocket guide strip 304 is detachably mounted on the side of the pressure plate 303 facing the sprocket 301. All of the above detachable connections can be made using bolt connections. The detachable connection of each component allows for convenient replacement and maintenance.

[0044] Preferably, when two reels 101 are provided, the sprocket 301 can be placed between the two reels 101 to reduce the adverse effects of the carriage tilting caused by the oil pipe pulling, which affects the stability of the oil pipe reel system.

[0045] It should be noted that the transmission mechanism is not limited to the chain and sprocket transmission mentioned above. Other transmission methods in the prior art that can enable the carriage 201 to move along the slide rail are also applicable to this application, and will not be described or limited here.

[0046] As an optional implementation, such as Figure 7 As shown, symmetrically arranged sliders 202 are mounted on the side of the carriage 201 opposite to the reel 101. Each slider 202 has an inclined slot 203, and the sliders 202 are connected to the carriage 201 by bolts 204 passing through the slot 203. Because of the slot 203, the installation position of the sliders 202 can be adjusted according to actual conditions, i.e., the spacing between the relatively arranged sliders 202 can be adjusted, thus making the carriage 201 suitable for slide rails of different widths.

[0047] Optionally, the reel 101 is provided with multiple storage slots 102, and the storage slots 102 are independent of each other, so that the oil pipes wound on each reel 101 do not rub against each other.

[0048] In addition, the width of the receiving groove 102 on the same reel 101 is the same, while the width of the receiving groove 102 on different reels 101 is different. At this time, different reels 101 can be used to wind oil pipes with different outer diameters.

[0049] It should be noted that the width of the storage slots 102 on all reels 101 can be the same, or the width of the storage slots 102 on the same reel 101 can be different.

[0050] To reduce friction between the oil pipe and the reel 101, thereby reducing oil pipe wear, optionally, a vertical shaft 104 is installed on the carriage 201, and the reel 101 is rotatably connected to the vertical shaft 104, for example, through a bearing. When the oil pipe is dragged, the friction between the oil pipe and the reel 101 will drive the reel 101 to rotate, thereby reducing the wear on the surface of the oil pipe.

[0051] In one embodiment, this application also proposes an engineering vehicle, such as a rock drilling rig, which includes the aforementioned tubing reel assembly.

[0052] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
