Description

Technical Field

[0001] This utility model relates to the field of explosives loading technology in tunnel construction, and in particular to an explosives loading vehicle for tunnel construction. Background Technology

[0002] During tunnel construction, manual drilling and loading of explosives may be required. Traditional loading typically involves setting up a platform where workers load explosives. This method allows for the construction of platforms based on the required working length, increasing the working area. However, the platforms are fixed in place and cannot be moved. Furthermore, the setup and dismantling are complex, resulting in low loading efficiency.

[0003] Chinese utility model patent CN222066743U discloses a fully hydraulic three-arm rock drilling rig, which has a suspended platform at the front end of the working platform arm. The suspended platform is used by workers to load explosives into the borehole. Since the rig can move, the loading efficiency is higher than that of setting up a scaffold. However, due to the working space required by the drilling arm, the working surface of the suspended platform in front of this type of rig is relatively short, generally only about 1 meter, which can only allow two workers to load explosives, thus greatly limiting its efficiency. Moreover, the suspended platform is completely fixed to the front end of the working platform arm and cannot be removed and replaced with a suspended platform with a larger working surface, thus limiting its working efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, such as the short working face of the basket working platform of the three-arm rock drilling rig, which greatly limits its charging efficiency, and to provide a charging engineering vehicle for tunnel construction.

[0005] In a first aspect, this utility model provides a tunnel construction explosive loading vehicle, comprising:

[0006] The vehicle body is a three-arm rock drilling rig, which includes a drill arm, and the vehicle body is movable.

[0007] A work platform arm, one end of which is connected to the vehicle body;

[0008] An existing work platform is fixed to the other end of the work platform arm;

[0009] The new loading platform has a detachable connection at its lateral center on the side closest to the working platform arm to the side of the existing working platform away from the working platform arm. The lateral length of the working surface of the new loading platform on the side away from the working platform arm is greater than the lateral length of the working surface of the existing working platform on the side away from the working platform arm.

[0010] The tunnel construction explosive loading vehicle of this utility model features a new explosive loading platform that can be detachably connected to the existing working platform of a three-arm drilling rig on the side furthest from the working platform arm. The existing working platform supports the lateral center of the new explosive loading platform on the side closest to the working platform arm, ensuring its lateral balance and providing a working surface and stable operating conditions. The detachable connection of the new explosive loading platform to the existing working platform allows it to be removed when the drill arm is needed, without affecting its operation. When more workers are required to load explosives simultaneously, the drill arm is not needed; the new explosive loading platform can be detachably connected to the existing working platform, using its support to ensure the loading conditions of the new platform without interference. Furthermore, the lateral length of the working surface of the new explosive loading platform on the side furthest from the working platform arm is greater than that of the existing working platform on the side furthest from the working platform arm, allowing more workers to load explosives on the new platform and thus improving loading efficiency.

[0011] Preferably, the new loading platform includes an operating platform and a hanging arm. The hanging arm is located on the side of the operating platform close to the working platform arm. The operating platform is hung on the side of the existing working platform away from the working platform arm via the hanging arm. The hanging arm and the guardrail on the side of the existing working platform away from the working platform arm are detachably locked by a locking device.

[0012] The operating platform is mounted on the side of the existing working platform away from the working platform arm by means of a hanging arm. Then, the hanging arm is detachably locked to the guardrail on the side of the existing working platform away from the working platform arm by means of a locking device. The hanging arm serves as a temporary support, which facilitates the locking operation of the locking device. At the same time, the hanging arm serves as a support structure during operation. With the locking device, the stability of the new loading platform is greatly improved.

[0013] Preferably, the hanging arm includes a vertical beam and a horizontal beam. The vertical beam and the operating platform can be installed on both sides of the guardrail on the side of the existing working platform away from the working platform arm. The vertical beam and the operating platform are connected by the horizontal beam. The horizontal beam is fixedly connected to the top of the vertical beam. The top of the guardrail on the side of the existing working platform away from the working platform arm supports the horizontal beam. The platform surface of the existing working platform supports the bottom of the vertical beam.

[0014] The locking component is a U-shaped fixing bolt. The curved section of the U-shaped fixing bolt passes through the vertical beam, and the straight sections at both ends of the U-shaped fixing bolt are located on the horizontal sides of the vertical guardrail on the side of the existing working platform away from the working platform arm. The straight sections at both ends of the U-shaped fixing bolt are locked to the operating platform by threads.

[0015] Preferably, the operating platform is provided with hanging arms on both sides of the horizontal direction, and the hanging arms are provided corresponding to the corners of the existing working platform;

[0016] Each of the aforementioned hanging arms is vertically locked by at least two spaced U-shaped fixing bolts.

[0017] Preferably, the hanging arm has an inverted U-shaped structure with the opening facing downwards, and the guardrail on the side of the existing work platform away from the work platform arm is adapted to enter the inverted U-shaped structure;

[0018] or,

[0019] The hanging arm has an inverted L-shaped structure. The vertical beam, the horizontal beam and the vertical operating railing on the side of the operating platform near the working platform arm form an inverted U-shaped groove. The guardrail on the side of the existing working platform away from the working platform arm is adapted to enter the inverted U-shaped groove.

[0020] Preferably, one of the two lateral sides of the new drug loading platform is provided with an openable door.

[0021] Preferably, the new loading platform has a lateral length of 2m-3m, a width of 0.9m-1.1m, and a height of 1.1m-1.3m.

[0022] Preferably, the operating railing is made of steel pipe or square tube.

[0023] Preferably, the work platform arm is capable of rotating up and down relative to the vehicle body, and the work platform arm is capable of extending and retracting along its axial direction.

[0024] Preferably, the drill arm is capable of rotating up and down relative to the vehicle body, and the drill arm is capable of extending and retracting along its axial direction.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] This utility model provides a charging vehicle for tunnel construction. A new charging platform is detachably connected to the existing working platform of a three-arm drilling rig on the side furthest from the working platform arm. The existing working platform supports the lateral center of the new charging platform on the side closest to the working platform arm, ensuring the lateral balance of the new charging platform and providing a working surface and stable working conditions for charging. The new charging platform is detachably connected to the existing working platform; when the drilling arm is needed, the new charging platform can be removed from the existing working platform without affecting its use. When more workers need to charge simultaneously, the drilling arm is not required, so the new charging platform can be detachably connected to the existing working platform, using the existing platform for support to ensure the charging conditions of the new charging platform. The lateral length of the working surface of the new charging platform on the side furthest from the working platform arm is greater than that of the existing working platform on the side furthest from the working platform arm, allowing more workers to charge on the new charging platform and thus improving charging efficiency.

[0034] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0035] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0036] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are set as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," "parallel," or "coaxial" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0037] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0038] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0039] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0040] Example 1

[0041] like Figures 1-6 As shown, a tunnel construction explosive loading vehicle includes: a vehicle body 1, a working platform arm 12, an existing working platform 121, and a new explosive loading platform 2.

[0042] The vehicle body 1 is a three-arm rock drilling rig, which includes drill arms 11. A three-arm rock drilling rig typically has three drill arms 11, each capable of independently changing its vertical tilt angle relative to the vehicle body 1, and each drill arm 11 capable of axial movement or extension / retraction. Figure 1 The lateral movement or extension / retraction of the arm allows for drilling, a common arrangement for three-arm rock drilling rigs. The rig body 1 is equipped with wheels, enabling movement, and a braking system to secure it in place after it has been moved to the working position. The movement or angle changes can be achieved using motor control, engine control, or hydraulic control, all of which are conventional techniques.

[0043] like Figure 1 As shown, one end of the working platform arm 12 is connected to the vehicle body 1, and the existing working platform 121 is fixed to the other end of the working platform arm 12. The working platform arm 12 can rotate vertically relative to the vehicle body 1, and it can extend and retract along its axial direction, allowing adjustment of the angle and height of the existing working platform 121. The new loading platform 2, located near the working platform arm 12, is detachably connected to the side of the existing working platform 121 away from the working platform arm 12 at its lateral center. This means the working platform arm 12 can adjust the vertical tilt angle and height of the new loading platform 2. The working platform arm 12 can be controlled by a motor or hydraulic cylinder, which is a mature existing technology.

[0044] The lateral length of the working surface of the new loading platform 2 on the side away from the working platform arm 12 is greater than the lateral length of the working surface of the existing working platform 121 on the side away from the working platform arm 12. This allows the number of construction workers who can load explosives on the new loading platform 2 at the same time to be greater than the number of construction workers who can load explosives on the existing working platform 121 at the same time, thereby enabling more construction workers to load explosives simultaneously and improving loading efficiency.

[0045] In optional implementations, such as Figure 2 As shown, the new loading platform 2 includes an operating platform 21 and a hanging arm 22. The hanging arm 22 is located on the side of the operating platform 21 near the working platform arm 12. The operating platform 21 is hung on the side of the existing working platform 121 away from the working platform arm 12 via the hanging arm 22. The hanging arm 22 and the guardrail on the side of the existing working platform 121 away from the working platform arm 12 are detachably locked by a locking device. By hanging the operating platform 21 on the side of the existing working platform 121 away from the working platform arm 12 via the hanging arm 22, and then detachably locking the hanging arm 22 and the guardrail on the side of the existing working platform 121 away from the working platform arm 12 via the locking device, the hanging arm 22 serves as a temporary support, facilitating the locking operation of the locking device. At the same time, the hanging arm 22, as a support structure during operation, greatly improves the stability of the new loading platform 2 in conjunction with the locking device.

[0046] like Figures 2-5 As shown, the operating platform 21 is provided with hanging arms 22 on both sides of its lateral direction, which improves stability. The hanging arms 22 are positioned at the corners of the existing working platform 121. Since the vertical bars of the guardrails at the corners of the existing working platform 121 are designed to be large, the hanging arms 22 are supported and locked at these points, resulting in greater stability.

[0047] The hanging arm 22 has an inverted U-shaped or inverted L-shaped structure, such as Figure 3 As shown, the hanging arm 22 has an inverted L-shaped structure. The hanging arm 22 includes only one vertical beam 221 and one horizontal beam 222. The horizontal beam 222 is fixedly connected to the top of the vertical beam 221. The vertical beam 221 and the corresponding horizontal operating railing on the side of the operating platform 21 closest to the working platform arm 12 are directly fixedly connected via the horizontal beam 222. The vertical beam 221 and the operating platform 21 can be installed on both sides of the guardrail on the side of the existing working platform 121 away from the working platform arm 12, i.e., as shown... Figure 2As shown, the vertical beam 221, the horizontal beam 222, and the vertical operating railing 211 on the side of the operating platform 21 near the working platform arm 12 form an inverted U-shaped groove. The guardrail on the side of the existing working platform 121 away from the working platform arm 12 fits into the inverted U-shaped groove, so that the operating platform 21 is hung on the side of the existing working platform 121 away from the working platform arm 12 by the hanging arm 22. This method uses the vertical operating railing 211 on the side of the operating platform 21 near the working platform arm 12 to form a limit, ensuring the stability of the hanging.

[0048] When the hanging arm 22 has an inverted U-shaped structure, the hanging arm 22 includes not only a vertical beam 221 and a horizontal beam 222, but also a vertical connecting part connected to the operating platform 21, i.e. Figure 6 As shown, the top of the vertical beam 221 and the top of the vertical connecting part are directly fixedly connected by the horizontal beam 222 to form an inverted U-shaped structure. The vertical connecting part is fixedly connected to the operating platform 21. The opening of the inverted U-shaped structure faces downward. The guardrail on the side of the existing working platform 121 away from the working platform arm 12 is adapted to enter the inverted U-shaped structure. This allows the operating platform 21 to be hung on the side of the existing working platform 121 away from the working platform arm 12 via the hanging arm 22, ensuring the stability of the hanging.

[0049] like Figure 2 As shown, the top of the guardrail on the side of the existing work platform 121 away from the work platform arm 12 supports the crossbeam 222, and the platform surface 1211 of the existing work platform 121 supports the bottom of the vertical beam 221, thereby improving the stability of the hanging.

[0050] like Figures 2-5 As shown, the locking component is a U-shaped fixing bolt 23. The curved section of the U-shaped fixing bolt 23 passes through the vertical beam 221, and the straight sections at both ends of the U-shaped fixing bolt 23 are located on the horizontal sides of the vertical guardrail on the side of the existing work platform 121 away from the work platform arm 12. The straight sections at both ends of the U-shaped fixing bolt 23 are locked to the operating platform 21 by threads. Figure 6 As shown, the vertical connecting part is fixedly connected to the operating platform 21. Locking washers are fixedly welded to both sides of the horizontal direction of the vertical connecting part. The straight sections of both ends of the U-shaped fixing bolt 23 pass through the corresponding locking washers and are then connected by bolts to form a lock. Figure 6 As shown.

[0051] Furthermore, each of the hanging arms 22 is vertically locked by at least two spaced U-shaped fixing bolts 23, which improves stability. Figure 3 and Figure 6As shown, each of the hanging arms 22 is vertically locked on the upper and lower sides by two spaced U-shaped fixing bolts 23, which provides high stability.

[0052] In this embodiment, as Figure 3 As shown, the operating platform 21 includes an operating base plate 212 and operating railings 211 surrounding the operating base plate 212. The operating railings 211 include horizontal and vertical configurations to ensure the safety of construction personnel when standing on the operating platform 21 to load the explosives. The operating railings 211 are made of steel pipe or square tubing, which are lightweight, strong, and suitable for use at heights. Furthermore, to facilitate access for construction personnel to the operating platform 21 and avoid affecting the loading of explosives, as well as to improve safety during loading, one of the two horizontal sides of the new loading platform 2 is equipped with an openable door 213, such as... Figure 3 As shown, an openable door 213 is provided on the left side. One side of the openable door 213 is connected to the vertical operating railing 211 on the left and right sides by a hinge. The other side of the openable door 213 can rotate around the hinge and is equipped with a lock to lock it. This structure of the openable door 213 is a conventional structure. The main purpose of this application is to set the openable door 213 on one of the two transverse sides of the new loading platform 2, so that construction personnel can enter the operating platform 21. This avoids setting it on the working surface side, which would affect loading, and also avoids setting it on the working surface side or the side near the working platform arm 12, which would cause structural instability or loading danger, thereby improving safety.

[0053] In this embodiment, the lateral length of the new loading platform 2 is 2m-3m, which can simultaneously accommodate more loading personnel and avoid insufficient support stability due to excessive length, as well as avoid interference with other structures; the width of the new loading platform 2 is 0.9m-1.1m, which meets the loading requirements while avoiding interference with other structures; the height of the new loading platform 2 is 1.1m-1.3m, ensuring the safety of loading.

[0054] The tunnel construction charging vehicle described in this embodiment detachably connects a new charging platform 2 to the existing working platform 121 of the three-arm drilling rig on the side away from the working platform arm 12. The existing working platform 121 supports the lateral center of the new charging platform 2 on the side closest to the working platform arm 12, ensuring the lateral balance of the new charging platform 2 and providing a working surface and stable operating conditions for charging. The new charging platform 2 is detachably connected to the existing working platform 121. When the drill arm needs to be used, the new charging platform 2 is removed from the existing working platform 121, and the existing working arm... Platform 121 itself does not affect the use of the drill arm; when more workers are needed to load explosives at the same time, the drill arm is not required. Therefore, the new explosive loading platform 2 can be detachably connected to the existing working platform 121, and the existing working platform 121 can be used for support to ensure the loading conditions of the new explosive loading platform 2; and the lateral length of the working face of the new explosive loading platform 2 away from the working platform arm 12 is greater than the lateral length of the working face of the existing working platform 121 away from the working platform arm 12, thereby allowing more workers to load explosives on the new explosive loading platform 2, thus improving the efficiency of explosive loading.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
