Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically to a concrete spraying high-altitude platform device and an integrated blasting and excavation trolley for inclined shaft construction. Background Technology

[0002] Currently, the construction of pumped storage inclined shafts in China primarily employs the traditional drill-and-blast method. This method utilizes a simple work platform, serving only as a platform for personnel and materials, lacking the functionality of a mechanical high-altitude work platform. Before drilling and blasting, tasks such as placing explosives, inserting anchor bolts, grouting, installing protective netting, and laying tracks all require workers to be suspended by safety ropes, posing significant risks and high labor intensity. After drilling and blasting, the surface concrete spraying protection of the inclined shaft tunnel is also carried out by workers using handheld concrete spray guns, resulting in harsh working conditions. Furthermore, for large-diameter tunnels, manual operation alone is insufficient to complete the entire spraying work for the inclined shaft tunnel. Utility Model Content

[0003] To address the problems in the background technology, this utility model proposes a high-altitude concrete spraying platform device for inclined shaft construction, which organically combines a high-altitude work platform and a concrete spraying device. In the early stage of blasting, it serves as a high-altitude work platform to complete preliminary work such as placing explosives, inserting anchor bolts, grouting, hanging protective nets, and laying tracks. In the later stage of blasting, it serves as a concrete spraying device to complete the concrete protective layer spraying operation on the tunnel surface.

[0004] The present invention adopts the following technical solution:

[0005] A high-altitude concrete spraying platform device for inclined shaft construction includes a working basket, a boom structure, and a concrete spraying mechanism. The boom structure includes a straight boom hinged between a work platform and the working basket. The concrete spraying mechanism is mounted on the working basket.

[0006] The aerial work platform has two modes: aerial work mode and concrete spraying mode. An upper leveling drive cylinder is hinged between the work platform and the straight boom, and a lower leveling drive cylinder is hinged between the straight boom and the work basket. The upper and lower leveling drive cylinders have a first state of linkage control and a second state of separate control. When the aerial work platform is in the aerial work mode, the upper and lower leveling drive cylinders are in the first state to keep the work basket level during movement. When the aerial work platform is in the concrete spraying mode, the upper and lower leveling drive cylinders are in the second state to make the spraying direction of the concrete spraying mechanism approximately parallel to the axis of the straight boom.

[0007] Optionally, it also includes a hydraulic control system, which includes an oil tank, a multi-way valve assembly, and a directional valve. The multi-way valve assembly is connected to the oil line between the oil tank and the upper leveling drive cylinder, and the directional valve is connected to the oil line between the oil tank and the lower leveling drive cylinder. The rod chamber of the upper leveling drive cylinder and the rod chamber of the lower leveling drive cylinder are connected through the directional valve, and the rodless chamber of the upper leveling drive cylinder and the rodless chamber of the lower leveling drive cylinder are connected through the directional valve. When the aerial work platform is in the aerial work state, the directional valve opens the oil line between the upper and lower leveling drive cylinders and disconnects the oil line between the oil tank and the lower leveling drive cylinder. When the aerial work platform is in the concrete spraying state, the directional valve disconnects the oil line between the upper and lower leveling drive cylinders and opens the oil line between the oil tank and the lower leveling drive cylinder.

[0008] Optionally, the boom structure further includes a boom slewing mechanism, with the straight boom hinged between the boom slewing mechanism and the work basket. The boom slewing mechanism is mounted on the work trolley and is used to drive the straight boom to rotate 360° in the horizontal direction. The upper leveling drive cylinder is hinged between the boom slewing mechanism and the straight boom.

[0009] Optionally, the boom slewing mechanism includes a boom slewing drive mechanism and a slewing turntable. The boom slewing drive mechanism includes a fixed end and a slewing end rotatably connected to the fixed end. The fixed end is mounted on the work platform, and the slewing end is fixed to the slewing turntable, which is hinged to the straight boom.

[0010] Optionally, a luffing drive cylinder is also hinged between the straight boom and the boom slewing mechanism, wherein the straight boom is a telescopic boom.

[0011] Optionally, the boom structure further includes a flying boom structure, which is hinged between the straight boom and the work basket and is used to drive the work basket to pitch. The leveling drive cylinder is hinged between the straight boom and the flying boom structure.

[0012] The boom structure includes a boom connecting seat, a swing cylinder seat, an upper boom, and a lower boom. The boom connecting seat, upper boom, swing cylinder seat, and lower boom are sequentially hinged together to form a near-parallelogram structure. The boom connecting seat is located near the straight boom, and its portion opposite to the straight boom extends toward the straight boom to be hinged to the straight boom. The swing cylinder seat is located near the work basket, and its portion opposite to the work basket extends toward the work basket to be connected to the work basket. A boom drive cylinder is provided between the upper boom and the lower boom.

[0013] The work basket and the swing cylinder base are connected by a work basket rotation drive mechanism, which is used to drive the work basket to rotate within a set range in the horizontal direction.

[0014] As a general inventive concept, this utility model also provides an integrated blasting and excavation trolley for inclined shaft construction, including a work trolley and the above-mentioned concrete spraying aerial platform device for inclined shaft construction.

[0015] Optionally, the concrete spraying aerial platform device for inclined shaft construction is installed at the front end of the working trolley in the direction of travel, or the concrete spraying aerial platform device for inclined shaft construction is slidably mounted on the working trolley and can move back and forth along the direction of travel of the working trolley so that it extends to the front of the working trolley or retracts to the top of the working trolley.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] This utility model discloses a high-altitude concrete spraying platform device for inclined shaft construction, which organically combines a high-altitude work platform and a concrete spraying device. By controlling the state of two leveling drive cylinders, specifically, in the early stages of blasting, the two leveling drive cylinders are linked to maintain the device in high-altitude operation mode, ensuring the working basket remains level during movement to guarantee the safety of personnel and materials within the basket. This allows for the completion of preliminary work such as placing explosives, inserting anchor bolts, grouting, installing protective netting, and laying tracks. In the later stages of blasting, when concrete spraying protection is required on the inclined shaft tunnel surface, since maintaining the working basket's level is no longer necessary, the two leveling drive cylinders are controlled independently to put the device in wet spraying mode. This ensures the spraying direction of the concrete spraying mechanism is as parallel as possible to the axis of the straight arm, achieving optimal concrete spraying results. Therefore, this device can achieve full-section coverage of high-altitude operations before blasting and post-blasting surface protection operations for each drilling and blasting advance without moving the main trolley; it greatly optimizes working conditions, offering high flexibility and safety.

Detailed Implementation

[0030] The embodiments of the present invention are described below with reference to the accompanying drawings, so that those skilled in the art can better understand and implement the present invention. However, the listed embodiments are not intended to limit the present invention. In the absence of conflict, the following embodiments and the technical features in the embodiments can be combined with each other, wherein the same components are indicated by the same reference numerals.

[0031] like Figures 1-3As shown, this embodiment provides a concrete spraying aerial platform device for inclined shaft construction, including a working basket 11, a boom structure 1, and a concrete spraying mechanism 5. The boom structure includes a straight boom 13, which is hinged between the work platform 4 and the working basket 11. The concrete spraying mechanism 5 is installed on the working basket 11.

[0032] The aerial work platform has an aerial work state and a concrete spraying state. An upper leveling drive cylinder 18 is hinged between the work platform 4 and the straight arm 13, and a lower leveling drive cylinder 19 is hinged between the straight arm 13 and the work basket 11. The upper leveling drive cylinder 18 and the lower leveling drive cylinder 19 have a first state of linkage control and a second state of separate control. When the aerial work platform is in the aerial work state, the upper leveling drive cylinder 18 and the lower leveling drive cylinder 19 are in the first state so that the work basket 11 always remains horizontal during movement. When the aerial work platform is in the concrete spraying state, the upper leveling drive cylinder 18 and the lower leveling drive cylinder 19 are in the second state so that the spraying direction of the concrete spraying mechanism 5 is approximately parallel to the direction of the straight arm axis.

[0033] Therefore, in the early stages of blasting, the two leveling drive cylinders are linked and controlled to keep the device in a high-altitude operation mode, ensuring that the working basket remains horizontal during movement and guaranteeing the safety of personnel and materials inside. This allows for the completion of preliminary work such as placing explosives, inserting anchor bolts, grouting, installing protective netting, and laying tracks. In the later stages of blasting, concrete spraying is required to protect the surface of the inclined shaft tunnel. Since it is no longer necessary to keep the working basket horizontal, the two leveling drive cylinders are controlled to operate independently, putting the device in wet spraying mode. This ensures that the spraying direction of the concrete spraying mechanism is as parallel as possible to the axis of the straight arm, thereby achieving better concrete spraying results.

[0034] In this embodiment, as Figure 4 and Figure 5 The device also includes a hydraulic control system, which comprises an oil tank 9, a multi-way valve assembly 7, and a directional valve 8. The multi-way valve assembly 7 is connected to the oil line between the oil tank 9 and the upper leveling drive cylinder 18. The directional valve 8 is connected to the oil line between the oil tank 9 and the lower leveling drive cylinder 19. The rod chamber of the upper leveling drive cylinder 18 and the rod chamber of the lower leveling drive cylinder 19 are connected through the directional valve 8, and the rodless chamber of the upper leveling drive cylinder 18 and the rodless chamber of the lower leveling drive cylinder 19 are connected through the directional valve 8. When the aerial work platform is in the aerial work state, the directional valve 8 opens the oil line between the upper leveling drive cylinder 18 and the lower leveling drive cylinder 19 and disconnects the oil line between the oil tank 9 and the lower leveling drive cylinder 19. When the aerial work platform is in the concrete spraying state, the directional valve 8 disconnects the oil line between the upper leveling drive cylinder 18 and the lower leveling drive cylinder 19 and opens the oil line between the oil tank 9 and the lower leveling drive cylinder 19.

[0035] In summary, in the hydraulic control system of this embodiment, the lower leveling drive cylinder 19 is provided with two oil circuits. One circuit is connected in series with the upper leveling drive cylinder 18 and connected to the main oil circuit through the balance valve 71. The other circuit is directly connected to the oil cylinder. The two oil circuits are equipped with a reversing valve 8 to switch the oil circuits, thereby realizing the switching between linkage control and individual control of the two leveling drive cylinders, and thus realizing the switching between the high-altitude operation mode and the wet spraying mode of this device.

[0036] In this embodiment, the boom structure 1 also includes a boom slewing mechanism 12, a straight boom 13 is hinged between the boom slewing mechanism 12 and the work basket 11, the boom slewing mechanism 12 is mounted on the work trolley 4 and is used to drive the straight boom 13 to rotate 360° in the horizontal direction, and the upper leveling drive cylinder 18 is hinged between the boom slewing mechanism 12 and the straight boom 13.

[0037] In this embodiment, the boom slewing mechanism 12 includes a boom slewing drive mechanism 121 and a slewing turntable 122. The boom slewing drive mechanism 121 includes a fixed end and a slewing end that is rotatably connected to the fixed end. The fixed end is mounted on the work platform 4, and the slewing end is fixed to the slewing turntable 122. The slewing turntable 122 is hinged to the straight boom 13.

[0038] In this embodiment, the straight boom 13 is a telescopic boom, which includes a telescopic outer boom 131 and a telescopic inner boom 132. A luffing drive cylinder 16 is also hinged between the straight boom 13 and the boom slewing mechanism 12. During high-altitude operations or wet spraying, the angle of the straight boom 13 in the vertical plane is controlled by the luffing drive cylinder 16. After the operation is completed, the telescopic boom 13 is arranged along the travel direction of the work trolley 4 by the luffing cylinder so that the device can be retracted into the work trolley 4.

[0039] The boom slewing drive mechanism 121 can be driven by a motor to rotate its slewing end; the motor can be mounted on the work platform 4. The slewing turntable 122 is arranged horizontally, thereby enabling the boom slewing drive mechanism to achieve 360° rotation of the device in the horizontal direction. By extending the telescopic inner boom 132 out of or retracting it into the telescopic outer boom 131, the work basket is driven to move forward or backward along the axis of the telescopic boom 13.

[0040] In this embodiment, the boom structure 1 also includes a flying boom structure 14, which is hinged between the straight boom 13 and the work basket 11 and is used to drive the work basket 11 to pitch. The leveling drive cylinder 19 is hinged between the straight boom 13 and the flying boom structure 14.

[0041] In this embodiment, the boom structure 14 includes a boom connecting seat 141, a swing cylinder seat 143, an upper boom 142, and a lower boom 144. The boom connecting seat 141, the upper boom 142, the swing cylinder seat 143, and the lower boom 144 are connected end to end in a parallelogram-like structure. The boom connecting seat 141 is located near the straight arm 13, and its portion opposite to the straight arm 13 extends toward the straight arm 13 and is hinged to the straight arm 13. The swing cylinder seat 143 is located near the work basket 11, and its portion opposite to the work basket 11 extends toward the work basket 11 and is connected to the work basket 11. A boom drive cylinder 17 is provided between the two long arms 142.

[0042] The extended end of the boom drive cylinder 17 is hinged to the boom connecting seat 141 and the hinged end of the upper boom 142. The fixed end of the boom drive cylinder 17 is hinged to both the upper boom 142 and the lower boom 144. The hinge position between the upper boom 142 and the boom drive cylinder 17 is about one-third of the way from the work basket 11, and the hinge position between the lower boom 144 and the boom drive cylinder 17 is about one-half of the way from the work basket 11.

[0043] In this embodiment, the working basket 11 and the swing cylinder seat 143 are connected by a working basket rotation drive mechanism 15, which is used to drive the working basket 11 to rotate within a set range in the horizontal direction.

[0044] Equipped with a boom structure, the vertical pitch angle can reach ±65°, allowing for vertical position adjustment of the aerial work basket without adjusting the telescopic boom. A rotating work platform mechanism allows for horizontal angle adjustment of the aerial work basket. This aerial work platform is highly flexible, safe, and has a wide operating range, achieving full cross-section coverage for each drilling and blasting advance without moving the main trolley.

[0045] The work basket rotation drive mechanism 15 enables the work basket to swing left and right at a small angle when the boom is not in motion, thus achieving fine adjustment of the work basket in the left and right directions.

[0046] Specifically, the work basket 11 includes a base plate 111 and a guardrail 112. The base plate 111 is horizontally arranged, and the guardrail 112 surrounds the upper surface of the base plate 111. That is, the work basket 11 is vertically arranged. Under the linkage control of the upper leveling drive cylinder 18 and the lower leveling drive cylinder 19, during the pitching process of the flying arm structure 14 driving the work basket 11, the base plate 111 of the work basket 11 always remains horizontal to ensure the safety of personnel and the stability of transported materials.

[0047] Specifically, the concrete spraying mechanism 5 is equipped with a nozzle swing, nozzle rotation, and nozzle sweeping drive mechanism, referring to... Figure 4The nozzle swing, nozzle rotation and nozzle sweeping drive mechanisms are all connected to the main oil circuit by the multi-way valve assembly 7, so as to realize flexible control of the concrete nozzle and achieve full coverage of concrete spraying on the surface of the inclined shaft tunnel.

[0048] Example 2

[0049] like Figure 6 and Figure 7 As shown, this embodiment provides an integrated blasting and excavation trolley for inclined shaft construction, including a work trolley 4 and a concrete spraying aerial platform device of embodiment 1, which is installed at the front end of the work trolley 4 in the direction of travel.

[0050] The work trolley 4 is located inside the excavated inclined shaft 6. The bottom surface of the inclined shaft 6 is covered with steel plates as a track surface for the work trolley 4 to travel on. Each section of the inclined shaft requires anchor bolt installation, grouting, installation of protective netting, track laying, and placement of explosives. After excavation, the surface of the inclined shaft tunnel needs to be sprayed with concrete for protection. Previously, these operations required workers to be suspended by safety ropes, which was highly dangerous and labor-intensive. This invention adds the concrete spraying aerial platform device of Embodiment 1 to the work trolley 4. It is equipped with an aerial work platform and a concrete spraying device, offering high flexibility, high safety, and a wide operational coverage. It can achieve full-section coverage of aerial work before blasting and post-blasting surface protection of the inclined shaft tunnel without moving the main trolley.

[0051] Example 3

[0052] like Figure 8 and Figure 9 As shown, this embodiment provides an integrated blasting and excavation trolley for inclined shaft construction, including a work trolley 4 and a concrete spraying aerial platform device of embodiment 1. The concrete spraying aerial platform device is slidably mounted on the work trolley 4 and can move back and forth along the travel direction of the work trolley 4 so that it extends to the front of the work trolley 4 or retracts to the top of the work trolley 4.

[0053] In this embodiment, the concrete spraying aerial platform device is installed on the work trolley 4 via a sliding mechanism 2 and a lifting mechanism 3.

[0054] In this embodiment, the sliding mechanism 2 includes a sliding trolley and a slide rail. The slide rail is installed on the work platform 4 and arranged along the travel direction of the work platform 4. The sliding trolley slides on the slide rail. The fixed end of the boom rotation drive mechanism 121 is connected to the sliding trolley. The lifting mechanism 3 is connected to the sliding trolley for driving the sliding trolley to slide along the slide rail 22 so that the concrete spraying aerial platform device extends to the front of the work platform 4 or retracts to the top of the work platform 4.

[0055] In this embodiment, the lifting mechanism 3 includes a winch, a reel, and a wire rope. The winch is fixed on the work trolley 4, the reel is rotatably mounted on the work trolley 4, one end of the wire rope is fixed to the winch, and the other end passes through the winch and the reel before being fixed to the sliding trolley.

[0056] In addition, locking mechanisms can be installed at both the upper and lower ends of the slide rail to lock the sliding trolley when the concrete spraying aerial platform device is retracted to the work platform 4 and during operation, respectively, to ensure the safety of personnel and equipment.

[0057] This embodiment, through the design of sliding mechanism 2 and lifting mechanism 3, enables the deployment and complete retraction of the concrete spraying aerial platform device. When fully retracted, it does not affect the operation of other action devices 41, thus greatly expanding the function of the drilling and blasting trolley.

[0058] The embodiments described above are merely preferred embodiments of this utility model. The terms "in one embodiment," "in another embodiment," "in yet another embodiment," or "in still another embodiment" used in this specification all refer to one or more of the same or different embodiments according to this disclosure.
