Description

Technical Field

[0001] The utility model relates to the field of tunnel construction, in particular to a drilling platform. Background Art

[0002] Small-section tunnels are widely used in water supply and diversion projects and geological cave exploration projects. Due to the limitation of the working surface of the tunnel project, large equipment cannot be used in small-section tunnels. Therefore, different tunnel construction drilling methods are often used to help the subsequent tunnel projects. Tunnel construction drilling is a very important construction process in tunnel projects. Its main purpose is to open holes during tunnel excavation to facilitate subsequent construction excavation and ventilation. However, the mainstream of drilling is still workers drilling with drilling rigs. Some holes at higher positions require workers to build scaffolding and then move the drilling machine (or down-the-hole drill) onto the scaffolding. After drilling each hole, the drilling machine is manually moved to the next drilling position, and then the next hole is drilled. Or multiple groups of drilling personnel perform drilling operations at the same time. Their working environment is relatively harsh and the labor intensity is extremely high. This operation is more troublesome, resulting in low drilling efficiency.

[0003] In the prior art, for example, a multifunctional tunnel boring machine disclosed in the authorization publication number CN113931580B can be adjusted within a certain range including height and position in left and right directions, thereby improving drilling efficiency. However, the height adjustment mechanism of the boring machine only has a motor for driving the base to rise and fall, a pair of corresponding threaded sleeves and threaded rods, and three guide rods for guiding. When adjusting the height, uneven force may occur, resulting in the base failing to reach a predetermined position. Alternatively, the boring machine may shake or the drilling may deviate due to uneven support force provided by the three guide rods and one threaded rod during drilling, which will further reduce the drilling efficiency. Utility Model Content

[0004] The utility model aims to provide a drilling platform, which can drill holes on the heading face of a small-section tunnel. The platform can movably adjust the drill bit to drill holes at different horizontal positions and longitudinal heights, and can avoid drilling rig shaking and drilling deviation to improve drilling efficiency.

[0005] In order to solve the above problems, the utility model is implemented according to the following technical solutions:

[0006] A drilling platform, comprising a drilling rig base, a drill bit, a drill rod, a drill rod support and a motor, wherein the drill bit is arranged at the front end of the drill rod, and the drill bit and the drill rod can protrude from the drilling rig base and drill forward, characterized in that it also comprises:

[0007] A lifting mechanism, the lifting mechanism comprising at least three push rod assemblies connected below the drilling rig base and used for lifting the height of the drilling rig base;

[0008] A universal wheel, the universal wheel being connected to the bottom of the push rod of the push rod assembly;

[0009] A fixed support mechanism, the fixed support mechanism includes a slide rail assembly connected to the lifting mechanism and a front end top fixture connected to the drilling rig base, the slide rail assembly and the front end top fixture can withstand the reaction force generated by drilling when drilling on the drilling platform.

[0010] Furthermore, the push rod assembly may be an electric push rod assembly or a hydraulic push rod assembly.

[0011] Furthermore, the universal wheel has a wheel clamp which can prevent the universal wheel from rotating when subjected to force.

[0012] Furthermore, the slide rail assembly of the fixed support mechanism includes a slide rail and a slide rod, the slide rod is provided with a first locking portion, and the slide rail is provided with a second locking portion, and the first locking portion and the second locking portion can engage with each other to keep the slide rail and the slide rod of the slide rail assembly relatively fixed.

[0013] Furthermore, the first locking portion and the second locking portion may be one type and another type of protrusions and locking grooves with an indefinite number distributed along the slide rail and the slide rod.

[0014] Furthermore, the protrusions and the slots are evenly distributed along the corresponding slide rails or the corresponding slide bars.

[0015] Furthermore, the front end top fixing member of the fixed support mechanism is connected to the front end of the drilling rig base which protrudes when the drill bit is drilling.

[0016] Furthermore, a dust-proof spray nozzle is provided, which is connected to the drilling rig base and can spray water when the drill bit is drilling.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The utility model uses a slide rail assembly connected to the lifting mechanism and a front end top fixing connected to the drilling rig base, specifically, the slide rail assembly is connected to the push rod assembly. When the drilling rig is drilling, the drilling platform is easily moved backwards by the reaction force generated by drilling. Conventional consideration is to apply a force that can offset the reaction force at the rear of the drilling platform to prevent the drilling platform from moving backwards. Here, the slide rail assembly is connected at the push rod assembly, including a slide rail and a slide rod that can be fixed to each other and can provide the required force for offsetting. On the other hand, considering that the drilling force of the drilling rig is changing in real time and is not fixed, the drilling platform may sometimes rock back and forth as a result. The front end fastener connected to the drilling rig base can resist the palm surface of the drill hole, and together with the offsetting force provided by the slide rail assembly, it can avoid the rocking of the drilling platform, so as to further improve the drilling efficiency.

[0019] The utility model realizes the function of adjusting the position of the drilling rig base up, down, left and right by arranging a push rod assembly for lifting the drilling rig base under the drilling rig base, and arranging a universal wheel capable of circumferential movement at the bottom of the push rod of the push rod assembly, so as to facilitate workers to complete drilling in various complex environments during construction.

[0020] The utility model is provided with a dust-proof spray nozzle capable of spraying water when drilling, the dust-proof spray nozzle can wet the flying dust or fine gravel generated by drilling and then slowly deposit on the ground, and assists workers in not being affected by the dust environment and reducing work efficiency when drilling.

[0021] In summary, the drilling platform of the present invention can improve drilling efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0029] In order to improve the drilling efficiency in the project and ensure the safety of workers at work, related technologies have previously achieved this goal through the connection of threaded sleeves and threaded rods and the structure of slideways that can quickly adjust the height and front, back, left and right positions of the drilling platform.

[0030] In order to solve this problem, the applicant provides a drilling platform.

[0031] like Figure 1-2 As shown, a preferred implementation of a drilling platform of the utility model.

[0032] A drilling platform comprises a drilling rig base 5, a drill bit 1 and a drill rod 7. The drill bit 1 is arranged at the front end of the drill rod 7, and the drill bit 1 and the drill rod 7 can protrude from the drilling rig base 5 to drill forward. It also comprises a lifting mechanism, universal wheels and a fixed support mechanism.

[0033] The lifting mechanism includes at least three push rod assemblies 8 connected to the bottom of the drilling rig base 5 for lifting the height of the drilling rig base 5; the universal wheel is connected to the bottom of the push rod of the push rod assembly 8; the fixed support mechanism includes a slide rail assembly connected to the lifting mechanism and a front end top fixture 13 connected to the drilling rig base 5, and the slide rail assembly and the front end top fixture 13 can withstand the reaction force generated by drilling when the drilling platform is drilling. In some embodiments, the push rod assembly 8 can be an electric push rod assembly or a hydraulic push rod assembly.

[0034] The drilling platform provided in the embodiment of the present application has a lifting mechanism including at least three groups of push rod assemblies 8 connected to the bottom of the drilling rig base 5 for lifting the height of the drilling rig base 5. The number of push rod assemblies 8 can be three groups, four groups or even more. This is because the drilling platform is generally used in the construction of the tunnel face, and the working conditions of the tunnel face construction are complex. When the number of push rod assemblies 8 is less than three groups, it is difficult to quickly find a stable stop position for the drilling platform in the tunnel, and it is further impossible to ensure that the drilling platform does not shake or deviate from the drilling when it is subjected to the reaction force generated by the drilling. In addition, the push rod assembly 8 can be an electric push rod assembly or a hydraulic push rod assembly. Both the electric push rod assembly and the hydraulic push rod assembly are commonly used for linear motion in industry. In some embodiments, the electric push rod assembly is selected for the purpose of adjusting the height of the drilling base and the small installation space required for the small tunnel section. In other embodiments, the hydraulic push rod assembly is selected for the purpose of requiring a large load on the drilling platform.

[0035] On the other hand, considering that the position of the drilling platform in the horizontal direction also needs to be adjusted, a universal wheel is connected to the bottom of the push rod of the push rod assembly 8 so that the drilling platform can be adjusted quickly before drilling.

[0036] In order to improve the drilling efficiency of tunnel construction in the current technology, one solution is to design a drilling machine with a group of threaded sleeves and threaded rods as the driving center, and with three groups of sliding sleeves, bare rods, and horizontal slide grooves. However, the applicant found that this type of drilling machine may have uneven force, causing the drilling machine to shake or the drilling to deviate. In order to solve this defect, in some embodiments, the fixed support mechanism includes a slide rail assembly 10 connected to the lifting mechanism and a front end top fixture 13 connected to the drilling rig base. The slide rail assembly 10 and the front end top fixture 13 can withstand the reaction force generated by drilling when drilling on the drilling platform.

[0037] Through the slide rail assembly 10 connected to the lifting mechanism and the front end top fastener 13 connected to the drilling rig base, specifically the slide rail assembly 10 is connected to the push rod assembly 8. When the drilling rig is drilling, the drilling platform is easily moved backwards by the reaction force generated by drilling. The conventional consideration is to apply a force that can offset the reaction force at the rear of the drilling platform to prevent the drilling platform from moving backwards. Here, the slide rail assembly 10 connected to the push rod assembly 8 includes a slide rail and a slide rod that can be fixed to each other and can provide the required force for offsetting. On the other hand, considering that the drilling force of the drilling rig is changing in real time and is not fixed, the drilling platform may sometimes rock back and forth. The front end fastener 13 connected to the drilling rig base 5 can resist the palm surface of the drill hole, and together with the offset force provided by the slide rail assembly 10, it can avoid the rocking of the drilling platform or the occurrence of drilling deviation.

[0038] In some embodiments, the universal wheel has a wheel clamp 9 that can prevent the universal wheel from rotating when subjected to force.

[0039] The drilling platform of the embodiment of the present application is combined with Figure 1 After the drilling platform is moved to the position where drilling is required during construction, the wheel clamp 9 provides resistance for the universal wheel to clamp, which can stabilize the drilling platform first and facilitate the subsequent adjustment of the height of the drilling rig base 5 of the drilling platform.

[0040] In some embodiments, the slide rail assembly 10 of the fixed support mechanism includes a slide rail and a slide rod, the slide rod is provided with a first locking portion, and the slide rail is provided with a second locking portion, the first locking portion and the second locking portion can engage with each other to keep the slide rail and the slide rod of the slide rail assembly 10 relatively fixed; the first locking portion and the second locking portion can be one type and another type of protrusions and grooves with an indefinite number distributed along the slide rail and the slide rod; the protrusions and grooves are evenly distributed along their corresponding slide rails or corresponding slide rods.

[0041] The drilling platform of the embodiment of the present application, the slide rail assembly 10 of the fixed support mechanism includes a slide rail and a slide rod, the slide rod is provided with a first clamping portion, the slide rail is provided with a second clamping portion, the first clamping portion and the second clamping portion can be engaged with each other so that the slide rail and the slide rod of the slide rail assembly remain relatively fixed, combined with Figure 1 The slide rail assembly 10 is arranged at the other end opposite to the drilling direction of the drill bit. When the drilling platform is drilling, the engaging parts of the slide rail assembly 10 are in direct contact with the ground. Only when the slide rail and the slide rod included in the slide rail assembly 10 are relatively fixed can the reaction force exerted on the drilling platform be offset by the slide rail assembly 10.

[0042] On the other hand, considering the complex tunnel construction environment, and in the preferred embodiment of the utility model of the present application, the height of the drilling base 5 is adjusted up and down by the push rod assembly 8, combined with Figure 1 to Figure 2 The first and second locking portions can be one and another type of protrusions and slots with an indefinite number of protrusions and slots distributed along the slide rail and the slide rod, and the protrusions and slots are evenly distributed along the corresponding slide rail or the corresponding slide rod, which can make the drilling platform more flexible when stopping and installing before drilling, and less affected by the working environment.

[0043] In some embodiments, the front end top fixing member 13 of the fixed support mechanism is connected to the front end of the drilling rig base 5 which protrudes when the drill bit 1 is drilling.

[0044] The front end top fixing member 13 of the fixed support mechanism of the drilling platform of the present application is connected to the front end of the drilling rig base 5 protruding when the drill bit 1 is drilling, and combined with Figure 1When the drilling platform is drilling, the palm surface exerts a reaction force on it. This reaction force is not fixed and there is no regularity as the tunnel construction goes deeper. It can be seen that only the additional slide rail assembly 8 cannot completely avoid the possible shaking of the drilling platform or the drilling deviation. The front end of the protruding drill rig base 5 when the drill bit 1 is drilling is connected to the front end top fixing piece 13, which can further help the drilling platform to achieve the purpose of not shaking or avoiding drilling deviation.

[0045] In some embodiments, the dust-proof spray nozzle 2 is connected to the drill base 5 and can spray water when the drill bit 1 is drilling.

[0046] The drilling platform of the embodiment of the present application, the dust-proof spray nozzle 2 is connected to the drill rig base 5, which can spray water when the drill bit 1 is drilling. Considering that the ventilation conditions in the tunnel are poor, the dust generated by drilling will quickly drift toward the direction of the drilling platform facing the palm surface as the drilling bit 1 goes deeper, making the working environment of the workers worse. They have to reduce work efficiency to ensure the safety of the workers and to ensure that there are no accidents at the drilling platform, which will further lead to reduced drilling efficiency. The dust-proof spray nozzle 2 is connected to the drilling rig base 5 so that it can spray water when the drill bit 1 is drilling, which can wet most of the flying dust or fine gravel generated by drilling and then slowly deposit on the ground, thereby assisting workers not to be affected by the dusty environment and reduce work efficiency when drilling.

[0047] The working principle of the drilling platform of the utility model is:

[0048] The utility model discloses a drilling platform, which includes a drilling rig base 5, a drill bit 1, a drill rod 7, a lifting mechanism, a universal wheel and a fixed support mechanism, wherein the lifting mechanism is connected to the bottom of the drilling rig base 5 and includes at least three push rod assemblies 8 capable of lifting the drilling rig base 5, the universal wheel is connected to the bottom of the push rod of the push rod assembly 8, and the fixed support mechanism includes a slide rail assembly 10 connected to the lifting mechanism and a front end top fixing 13 connected to the drilling rig base 5. The drilling platform provided by the utility model can adjust the height and front, back, left and right positions of the drilling platform through the lifting mechanism and the universal wheel, and can avoid the drilling platform from being offset due to the shaking of the unbalanced force on the drilling platform through the fixed support mechanism.

[0049] In summary, the drilling platform of the present invention can improve drilling efficiency and avoid shaking of the drilling platform and drilling deviation.

[0050] For other structures of the drilling platform of this embodiment, refer to the prior art.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
