Description

Technical Field

[0001] This utility model belongs to the field of coal mine transportation technology, specifically, it relates to a supporting transportation device for a directional drilling rig. Background Technology

[0002] Near-horizontal directional drilling technology refers to a drilling method that utilizes the natural curvature of the borehole or employs special tools to extend the near-horizontal borehole trajectory to a predetermined target according to design requirements, that is, intentionally changing the borehole axis from curved to straight or from straight to curved.

[0003] Existing technology discloses a tracked drill pipe transport vehicle (CN220447991U), including a tracked chassis, a platform, and a drive mechanism. The platform is fixed to the tracked chassis; the platform is used to hold drill pipes and drilling tools; the drive mechanism is located on the upper surface of the platform; the drive mechanism includes a diesel engine, a gear shifting mechanism, and a steering lever. Due to the tracked chassis, the transport vehicle has good climbing ability and stable maneuverability, maintaining stability even on steep roads, improving operational stability and safety when traveling in mountainous areas, and preventing rollovers. Simultaneously, the long tracked chassis ensures the drill pipes are very stable on the transport vehicle. This utility model solves the transportation problems encountered in mountain construction, saving time and ensuring safety and stability, bringing great convenience to mountain construction, and providing convenience for work by combining safety and economy.

[0004] Research revealed that tracked structures have a large turning radius, making them unsuitable for narrow coal mine tunnels; the traction connection is prone to stress concentration due to rigid angles, leading to component damage and affecting equipment lifespan; the drill rod is only fixed by simple supports, and the tracked structure has poor braking performance, making it prone to slippage; during coal mine transportation, vehicle bumps can easily cause the drill rod to slide and collide, posing safety hazards and easily damaging the drill rod, increasing operation and maintenance costs, and making it unsuitable for complex working conditions.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A transport device for a directional drilling rig, comprising:

[0008] The frame has a rear wheel and two front wheels rotatably mounted at its bottom, and a clamping frame is mounted on its top surface.

[0009] A braking assembly is movably disposed between two front wheels. The braking assembly includes a brake plate, an arc-shaped toothed plate, a connecting rod, and a swing rod. Each front wheel is movably provided with a swing rod, a pair of arc-shaped toothed plates, and a pair of connecting rods. The brake plate is fixedly disposed between the two swing rods, and the two connecting rods are hinged between the arc-shaped toothed plates and the swing rods.

[0010] In a preferred embodiment of the present invention, the clamping frame includes a triangular rigid bracket and a side bracket. Two toothed plates are symmetrically fixed on the top surface of the frame. Two side brackets are symmetrically arranged. The side brackets are fixedly connected to the top surface of the frame. A triangular rigid bracket is fixedly installed at one end of the top surface of the frame, and another triangular rigid bracket is slidably arranged at the other end of the top surface of the frame.

[0011] In a preferred embodiment of the present invention, two sliding chambers are symmetrically provided on the top surface of the frame. Two through shafts are symmetrically fixed in one of the sliding chambers, and a slider is fixed at the bottom of one of the triangular rigid brackets. The slider slides between the two through shafts and the sliding chamber.

[0012] In a preferred embodiment of this utility model, two disc spring assemblies are symmetrically fixed between the slider and the inner wall of the sliding chamber. The disc spring assemblies are sleeved on the through shaft, and the slider is elastically connected to the sliding chamber through the two disc spring assemblies.

[0013] In a preferred embodiment of this utility model, a support base and four support plates are fixedly provided at the bottom of the frame. The four support plates and the support base are symmetrically arranged at both ends of the bottom surface of the frame. The rear wheel is rotatably arranged in the support base, and a front wheel is rotatably arranged in each pair of support plates.

[0014] In a preferred embodiment of this utility model, a brake cylinder is fixedly provided on each of the two front wheels that are close to each other, the brake plate is hinged between the two central support plates, and a pull rod is hinged to the end of the brake plate away from the frame.

[0015] In a preferred embodiment of this utility model, the brake cylinder is provided with an annular tooth groove, and the arc-shaped toothed plate engages with the annular tooth groove. The two central support plates are symmetrically fixed with two support shafts on the side near the brake cylinder. The two central support plates are each hinged to an arc-shaped toothed plate through the two support shafts. The swing rod is fixedly connected to the brake plate and is hinged to the side of the two central support plates away from the brake plate.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. Both the front and rear wheels adopt a rubber-tired structure. The compact frame design replaces tracks, allowing for flexible movement in coal mine roadways and solving the problem of getting stuck in narrow roadways. Two toothed plates jointly support the drill rod, side brackets on both sides prevent the drill rod from sliding, and two triangular brackets work with disc springs to adaptively limit the length of the drill rod. This five-sided constraint prevents the drill rod from sliding and causing collision damage, thereby avoiding increased maintenance costs.

[0018] 2. The brake plate swings synchronously with the swing rod, which in turn pushes the arc-shaped toothed plate to rotate around the support shaft and engage the ring tooth groove of the brake cylinder through the connecting rod, thereby locking the front wheel. In the opposite direction, the brake plate is pushed to swing up, and the arc-shaped toothed plate disengages from the ring tooth groove, restoring the rotation of the front wheel. The toothed braking between the arc-shaped toothed plate and the brake cylinder reduces the risk of slippage. It has no complex electrical control components and is suitable for dusty and humid environments in coal mines, enabling the device to be used under complex working conditions.

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] A supporting transportation device for a directional drilling rig, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, including

[0029] a frame 10, the bottom of the frame 10 is rotatably provided with rear wheels 11 and two front wheels 12, and a clamping frame is installed on the top surface of the frame 10; as Figure 2 shown, a support base 17 and four support plates 16 are fixedly provided at the bottom of the frame 10, the four support plates 16 and the support base 17 are symmetrically arranged at both ends of the bottom surface of the frame 10, the rear wheel 11 is rotatably arranged in the support base 17, and a front wheel 12 is rotatably arranged in each pair of support plates 16;

[0030] A braking component, the braking component is movably arranged between the two front wheels 12, the braking component includes a brake plate 24, an arc-shaped toothed plate 25, a connecting rod 26 and a swing rod 27, a swing rod 27, a pair of arc-shaped toothed plates 25 and a pair of connecting rods 26 are movably arranged in each front wheel 12, the brake plate 24 is fixedly arranged between the two swing rods 27, and the two connecting rods 26 are hinged between the arc-shaped toothed plate 25 and the swing rod 27.

[0031] Specifically, the frame 10 is made of a rectangular steel frame, serving as the installation reference for all functional modules. The rear wheel 11 is rotatably connected to the inside of the support base 17 through a bearing rotating shaft; the two front wheels 12 are respectively rotatably connected between the two support plates 16. The support plates 16 are symmetrically welded to both ends of the bottom surface of the frame, and are distributed in a triangular shape with the support base 17. The support base 17, the frame 10, the front wheels 12 and the rear wheels 11 all adopt rubber wheel structures. The two replace the crawler with a compact frame 10 design, which can move flexibly in the coal mine roadway and solve the problem of jamming in narrow roadways. By setting the clamping frame, the drill pipe is limited and constrained from five sides by the clamping frame, and the drill pipe is prevented from being damaged by collision caused by sliding, thereby avoiding the increase of operation and maintenance costs. The braking component can mechanically brake the device when parking is required during the transportation of the drill pipe, reducing the risk of vehicle slipping. There are no complex electronic control components, which can adapt to the coal mine dust and humid environment, enabling the device to adapt to complex working conditions.

[0032] As Figure 1 , Figure 2 and Figure 3As shown, the clamping frame includes a triangular rigid bracket 14 and a side bracket 15. Two toothed plates 18 are symmetrically fixed on the top surface of the frame 10. Two side brackets 15 are symmetrically arranged. The side brackets 15 are fixedly connected to the top surface of the frame 10. The two side brackets 15 and the two toothed plates 18 are oriented in different directions. The two side brackets 15 are arranged symmetrically in the longitudinal direction. The two toothed plates 18 are arranged symmetrically in the transverse direction. The two toothed plates 18 are used to support the drill rod together. A triangular rigid bracket 14 is fixedly installed at one end of the top surface of the frame 10. Another triangular rigid bracket 14 is slidably arranged at the other end of the top surface of the frame 10.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, two sliding chambers 20 are symmetrically opened on the top surface of the frame 10. Two through shafts 19 are symmetrically fixed in one of the sliding chambers 20. A slider 22 is fixed at the bottom of one of the triangular rigid brackets 14. The slider 22 slides between the two through shafts 19 and the sliding chamber 20. Two through holes are symmetrically opened on the slider 22, corresponding to the two through shafts 19. The through holes slide on the through shafts 19. The slider 22 is a block and slides in conjunction with the sliding chamber 20.

[0034] like Figure 2 and Figure 3 As shown, two disc spring assemblies 23 are symmetrically fixed between the slider 22 and the inner wall of the sliding chamber 20. The disc spring assemblies 23 are fitted together on the through shaft 19, and the slider 22 is elastically connected to the sliding chamber 20 through the two disc spring assemblies 23.

[0035] Specifically, the triangular rigid bracket 14 adopts a triangular frame, divided into a fixed end bracket welded to one end of the top surface of the frame 10 and a sliding end bracket connected to the sliding chamber 20 via the slider 22; the side bracket 15 is a steel plate structure, longitudinally symmetrically welded to both sides of the top surface of the frame 10, parallel to the longitudinal axis of the frame 10; the toothed plate 18 is an arc-shaped toothed steel plate, with a tooth pitch adapted to the drill rod diameter, laterally symmetrically welded to the middle of the top surface of the frame 10, perpendicular to the longitudinal axis of the frame 10; the sliding chamber 20 is a rectangular groove symmetrically opened on the top surface of the frame 10, one of which contains a through shaft 19 and two disc springs. The assembly 23 and slider 22 are welded and fixed to the triangular rigid bracket 14. The slider has a square structure and is adapted to the size of the sliding chamber. The slider 22 and the through shaft 19 achieve longitudinal sliding through the through hole sliding cooperation. One end of the disc spring assembly 23 abuts against the slider 22 and the other end abuts against the inner wall of the sliding chamber 20, providing elastic preload. The preload is adjusted by the number of disc springs. The two toothed plates 18 jointly support the drill rod. The side brackets 15 on both sides are used to prevent the drill rod from sliding. The two triangular brackets 14 cooperate with the disc spring assembly 23 to adapt and limit the length of the drill rod, constraining it from five sides to prevent rolling during transportation.

[0036] like Figure 2 , Figure 4 and Figure 5 As shown, a brake cylinder 21 is fixed on the side of each of the two front wheels 12 that are close to each other. The brake plate 24 is hinged between the two support plates 16 in the center. A pull rod 13 is hinged to the end of the brake plate 24 away from the frame 10. A hinge shaft is fixed on each side of the brake plate 24. The brake plate 24 is hinged to the two support plates 16 in the center through the hinge shafts on both sides.

[0037] like Figure 2 and Figure 5 As shown, the brake cylinder 21 has an annular tooth groove 28, and the arc-shaped toothed plate 25 engages with the annular tooth groove 28. One end of the arc-shaped toothed plate 25 is hinged to the support shaft. The outer curved surface of the arc-shaped toothed plate 25 is provided with serrations, which engage with the annular tooth groove 28. The connecting rod 26 is hinged between the inner curved surface of the arc-shaped toothed plate 25 and the swing rod 27. Two central support plates 16 are symmetrically fixed with two support shafts on the side near the brake cylinder 21. The two central support plates 16 are respectively hinged to an arc-shaped toothed plate 25 through the two support shafts. The swing rod 27 is fixedly connected to the brake plate 24 and is hinged to the side of the two central support plates 16 away from the brake plate 24.

[0038] Specifically, the brake plate 24 is hinged to the two central support plates 16 via hinge pins on both sides. The arc-shaped toothed plate 25 has a sawtooth shape that matches the annular groove 28 inside the brake cylinder 21. It is hinged to the two central support plates 16 near the brake cylinder 21 via a support shaft. The two ends of the connecting rod 26 are hinged to the arc-shaped toothed plate 25 and the swing rod 27 via pins. The swing rod 27 is welded and fixed to one side of the brake plate 24 via a hinge pin, and is also hinged to the two central support plates 16 away from the brake plate 24 via a hinge pin. The brake cylinder 21 is welded and fixed to the inside of the front wheel 12 via a column shaft. When parking is required, the operator presses down the pull rod 13. The brake plate 24 swings downward around the hinges on both sides, causing the swing rod 27 to swing synchronously. The swing rod 27 pushes the arc-shaped toothed plate 25 to rotate around the support shaft through the connecting rod 26. The arc-shaped tooth 25 engages with the ring tooth groove 28 to lock the front wheel 12. When the brake is released, the pull rod 13 is pushed in the opposite direction, the brake plate 24 swings upward, and the arc-shaped toothed plate 25 disengages from the ring tooth groove 28, restoring the rotation of the front wheel 12. At this time, the direction of movement of the device can be controlled by the pull rod 13.
