Technical Field
[0001] This utility model belongs to the field of rotary drilling rig technology, specifically relating to a rotary drilling rig and its protective platform device. Background Technology
[0002] In the field of foundation engineering construction, rotary drilling rigs, with their high efficiency and flexible hole-forming advantages, have become the core equipment for pile foundation construction and are widely used in major projects such as bridges, high-rise buildings, and rail transit. As my country's infrastructure construction moves towards larger scale and deeper foundation pits, the market is placing higher demands on the operational capabilities of rotary drilling rigs, leading to a clear trend towards larger models. At the same time, the deepening of the concept of safe construction has made the safety performance of rotary drilling rigs a core indicator in the research, development, production, and application of the equipment. This not only relates to the safety of construction personnel but also directly affects project progress and construction efficiency. Therefore, improving the safe operability and ease of maintenance of large rotary drilling rigs has become an urgent need for the industry's development.
[0003] However, the structural design of large rotary drilling rigs faces new challenges, with the installation layout of the main winch being particularly prominent. As a key actuator of the rotary drilling rig, the diameter and length of the main winch increase significantly with the size of the machine. To fit the overall structure, it is typically mounted horizontally in the rear of the roof. This installation method results in the main winch's total length completely occupying the width of the roof, creating a lateral obstruction and preventing maintenance personnel from accessing the rear of the roof from the front via the sides of the main winch for repairs. More critically, when the main winch's reducer malfunctions and requires repair, its compact installation structure leads to extremely limited operating space. This not only significantly increases the difficulty of disassembling the reducer and prolongs the repair cycle, but also compromises the stability of maintenance personnel, posing serious safety hazards and hindering the improvement of equipment maintenance efficiency and safety performance. Therefore, there is an urgent need for a rotary drilling rig and its protective platform device. Utility Model Content

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0015] like Figures 1 to 4 As shown, this utility model discloses a rotary drilling rig and its protective platform device.
[0016] On one hand, this utility model discloses a protective platform device for a rotary drilling rig. The protective platform device 1 is respectively set on both sides of the main winch 2 on the rotary drilling rig. Mounting brackets 6 are respectively set on both sides of the rotary drilling rig. The protective platform device for the rotary drilling rig includes a maintenance platform 5 set on one side of the rotary drilling rig via multiple mounting components, multiple guardrails 4 vertically set on the edge of the maintenance platform 5, and connecting components connecting the guardrails 4. The guardrails 4 are connected to the mounting brackets 6 via the connecting components. The guardrails 4 adopt a modular design, spliced from multiple round tubes 402 by welding or threaded connection to form a mesh protective structure. Its height is adapted to the waist level of a person, effectively preventing maintenance personnel from accidentally falling. The guardrails 4 are detachably connected to each other and to the mounting brackets 6 via connecting components. The maintenance platform 5 includes an anti-slip plate 501 and a side plate 502 disposed on the outer end face of the anti-slip plate 501. More specifically, the side plate 502 is vertically welded to the outer end face of the anti-slip plate 501 to form a lateral protective structure of the maintenance platform 5. Its height is adapted to the ankle position when a person is standing. Multiple fixing plates 508 are vertically connected to the side wall of the side plate 502. An mounting plate 403 is vertically connected above the fixing plate 508. The guardrail 4 is vertically connected to the fixing plate 508 above the mounting plate 403. The mounting assembly includes a mounting base 504 connected to one side of the rotary drilling rig by fasteners, and an ear plate 505 set on the top edge of the anti-slip plate 501. The mounting base 504 and the ear plate 505 are hinged by a pin 507. A bushing 506 is also provided between the ear plate 505 and the mounting base 504 on both sides. A locking pin is provided at the end of the pin 507, and a pin hole is provided at the end of the pin 507. After the locking pin is inserted into the pin hole, the pin 507 can be axially positioned to prevent the pin 507 from falling off during operation. The mounting base 504 and the ear plate 505 are hinged by the pin 507. The pin 507 passes through the corresponding through holes of the mounting base 504 and the ear plate 505, and bushings 506 are sleeved at both ends of the pin 507. The bushings 506 are made of wear-resistant metal material, which can reduce the relative wear between the pin 507 and the ear plate 505, improve the service life of the hinge structure, and effectively limit the axial displacement of the ear plate 505 through the bushings 506. The connecting assembly includes a connecting pipe 401 and a guardrail clamp assembly 3 disposed at the end of the connecting pipe 401. The guardrail clamp assembly 3 includes a first guardrail clamp 301 and a second guardrail clamp 302 symmetrically arranged. The first guardrail clamp 301 and the second guardrail clamp 302 are fixed together by fasteners. One end of the first guardrail clamp 301 and the second guardrail clamp 302 is sleeved on the outer periphery of the connecting pipe 401, and the other end is joined to form a mounting hole. The mounting hole matches the guardrail 4 and the mounting bracket 6. More specifically, the first guardrail clamp 301 and the second guardrail clamp 302 have the same structure and have arc-shaped grooves on their opposite surfaces. When the two pass through... When the fastener is clamped, the arc-shaped groove at one end can be assembled into a circular hole that fits the outer circumference of the connecting pipe 401, thus fixing it to the connecting pipe 401; the arc-shaped groove at the other end can be assembled into a mounting hole that fits the circular pipe 402 of the guardrail 4 or the mounting bracket 6, thus completing the connection with the corresponding component. During the installation process, the depth of the connecting pipe 401 inserted into the guardrail clamp assembly 3 can be adjusted according to the actual spacing. When there is a spacing deviation between the two guardrails 4 or between the guardrail 4 and the mounting bracket 6 due to manufacturing errors, only the insertion length of the connecting pipe 401 needs to be adjusted to achieve precise docking, effectively improving the installation adaptability of the device.
[0017] In one specific embodiment, in the protective platform device of the rotary drilling rig of this utility model, one end of the connecting component is sleeved on the guardrail 4 through the mounting hole, and the other end is sleeved on the mounting bracket 6 through the mounting hole.
[0018] In one specific embodiment, in the protective platform device of the rotary drilling rig of this utility model, the guardrail 4 is formed by splicing together multiple round tubes 402. One end of the connecting component is sleeved on the round tube 402 through the mounting hole, and the other end is sleeved on the round tube 402 of the adjacent guardrail 4 through the mounting hole.
[0019] As a specific implementation, in the protective platform device of the rotary drilling rig of this utility model, multiple anti-slip holes are evenly provided on the anti-slip plate 501, and protrusions are provided on the periphery of the anti-slip holes. This design can effectively increase the friction coefficient between the foot and the plate surface, preventing maintenance personnel from slipping in wet or oily conditions. At the same time, the anti-slip holes can realize the function of drainage and slag discharge, preventing the accumulation of impurities from affecting operational safety.
[0020] In one specific embodiment, in the protective platform device of the rotary drilling rig of this utility model, a plurality of shock-absorbing pads 503 are provided between the side plate 502 and the rotary drilling rig. The shock-absorbing pads 503 are fixed to one side of the side plate 502 by fasteners. More specifically, the shock-absorbing pads 503 are made of elastic wear-resistant material. When the maintenance platform 5 is in working condition, the shock-absorbing pads 503 are tightly fitted to the side of the main platform support of the rotary drilling rig. This arrangement can buffer the vibration generated during the operation of the equipment, prevent the vibration from causing the component connections to loosen, and extend the service life of the device.
[0021] As a specific embodiment, in the protective platform device of the rotary drilling rig of this utility model, a reinforcing rib 509 is provided between the fixed plate 508 and the side plate 502, and a reinforcing rib 509 is provided between the guardrail 4 and the mounting plate 403. The reinforcing rib 509 adopts a triangular plate structure and is welded and fixed to the two connecting surfaces respectively, which can effectively distribute the force and avoid the problem of cracking of the welding point caused by long-term load.
[0022] On the other hand, this utility model also provides a rotary drilling rig, which includes the above-mentioned protective platform device.
[0023] The working principle of the protective platform device for rotary drilling rigs of this utility model is as follows: First, the mounting base 504 is fixed to the preset position on the body of the rotary drilling rig using fasteners. Then, the ear plate 505 of the maintenance platform 5 is aligned with the mounting base 504, the pin 507 is inserted, and the locking pin is installed to complete the hinged installation of the maintenance platform 5. Next, the guardrail 4 is fixed to the mounting plate 403 of the maintenance platform 5 through the connecting component. At the same time, the guardrail 4 is connected to the mounting bracket 6 of the rotary drilling rig through the connecting component to achieve double fixation of the guardrail 4. When the main winch 2 reducer needs to be repaired, maintenance personnel can reach the rear of the roof from the front of the rotary drilling rig through the maintenance platforms 5 on both sides of the main winch 2, stand on the anti-slip plate 501 to carry out maintenance work. The guardrail 4 provides reliable protection, and the ample operating space facilitates the placement of tools and the disassembly of parts. When the whole machine needs to be transported, the fasteners of the connecting components are removed, the fasteners between the fixing plate 508 and the mounting plate 403 are pulled out, the guardrail 4 is removed, the main winch 2 is disassembled, and the maintenance platform 5 is flipped up around the pin shaft 507 to the top of the whole machine cover and temporarily fixed, so that the device can be stored and the transportation size requirements are met.
[0024] In summary, compared with the prior art, the rotary drilling rig and its protective platform device of this utility model have the following advantages and beneficial effects: (1) The protective platforms set on both sides of the main winch 2 of this device can provide a safe passage for maintenance personnel, enabling them to reach the rear of the vehicle roof smoothly. At the same time, the maintenance platform 5 provides sufficient space for maintenance work, ensuring operational stability and safety. The hinged structure of the installation components allows the maintenance platform 5 to be flipped and stored. Combined with the convenient disassembly and assembly design of the connecting components, the disassembly and assembly efficiency of the device is greatly improved, meeting the transportation needs of the whole machine. (2) The device is equipped with a shock-absorbing pad 503, which can effectively buffer the vibration of the equipment. The guardrail clamp assembly 3 can compensate for manufacturing errors by adjusting the insertion length of the connecting pipe 401 and improve the installation adaptability. The reinforcement rib 509 enhances the connection strength of each component. The raised structure of the anti-slip plate 501 further improves the safety of operation.
