[0010] intermeshing drive chains and drive gears; and

[0011] A power gear, the power gear is meshed with the driving gear;

[0012] Among them, in the vehicle body and the sliding seat, one of them is fixedly provided with a driving chain, and the other is provided with a driving gear.

[0013] The structure is simple and easy to assemble. Through the cooperation of the driving chain and the driving gear, the driving gear can be moved along the driving chain to realize the sliding of the sliding seat relative to the vehicle body.

[0014] Preferably, the driving mechanism further comprises:

[0015] The tensioning gear is located at one side of the driving gear and is used to bend the driving chain to increase the contact area between the driving gear and the driving chain.

[0016] The tensioning gear can realize the tensioning of the driving chain to ensure the power output. At the same time, since the contact area between the driving gear and the driving chain is increased, the power output capacity is also greatly improved.

[0017] Preferably, tensioning gears are provided on both sides of the driving gear.

[0018] The tensioning gears arranged on both sides of the driving gear further increase the contact area between the driving gear and the driving chain, thereby better ensuring the power output.

DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0039] like Figure 1 to Figure 4 As shown, a tunnel construction trolley includes a vehicle body 1 and a sliding seat 2, wherein a driving mechanism is arranged between the vehicle body 1 and the sliding seat 2; at least one working device and a driving cabin 3 are arranged on the sliding seat 2, wherein a construction workbench 4 is arranged in the driving cabin 3.

[0040] In this embodiment, a chassis 5 and front and rear axles are provided on the vehicle body 1. The chassis 5 has a load-bearing capacity. The front and rear axles are fixed on the chassis 5 to realize the load-bearing and driving functions of the chassis 5. Furthermore, the sliding seat 2 is installed on the chassis 5, that is, the sliding seat 2 and the chassis 5 are slidably connected to realize relative movement with the vehicle body 1.

[0041] like Figure 2 and Figure 3 As shown, in this embodiment, the driving mechanism includes a driving chain 6 and a driving gear 7 that mesh with each other, and a power gear 8; the power gear 8 meshes with the driving gear 7; in the vehicle body 1 and the sliding seat 2, one of them is fixedly provided with the driving chain 6, and the other is provided with the driving gear 7. Specifically, the power gear 8 is provided on the sliding seat 2, which has a motor 9 for driving it to rotate, the two ends of the driving chain 6 are fixed on the chassis 5, and the driving gear 7 is provided on the sliding seat 2. When the driving gear 7 is powered by the power gear 8, the driving gear 7 crawls along the driving chain 6, thereby driving the sliding seat 2 to move along the length direction of the driving rack. It is known that in some other technical solutions of this embodiment, the driving mechanism can also be a cylinder driving mechanism, a magnetic suspension mechanism, a gear rack mechanism, a linear motor mechanism, a screw nut mechanism, etc. Furthermore, in order to ensure sliding stability, a guide mechanism is further provided between the vehicle body 1 and the sliding seat 2; the guide mechanism includes a slide rail 10 and a slider 11; in the vehicle body 1 and the sliding seat 2, one of them is provided with a slide rail 10, and the other is provided with a slider 11. Specifically, the two ends of the chassis 5 in the width direction of the vehicle body 1 are configured as slide rails 10, and the sliding block is provided with a plurality of pairs of sliders 11 respectively matched with the two slide rails 10, so that when the driving gear 7 rotates, the slider 11 slides along the extension direction of the slide rail 10 to better meet the requirements of sliding stability.

[0042] In order to ensure the power output efficiency and stability of the driving mechanism, the driving mechanism also includes a tensioning gear 12, which is located on one side of the driving gear 7 and is used to bend the driving chain 6 to increase the contact area between the driving gear 7 and the driving chain 6. Specifically, the tensioning gear 12 is arranged on the sliding seat 2, and further, tensioning gears 12 are arranged on both sides of the driving gear 7. It can be seen that the driving gear 7 can be equipped with multiple pairs of tensioning gears 12. In this embodiment, a pair of tensioning gears 12 is taken as an example. A tensioning gear 12 is arranged on both sides of the driving gear 7. The two tensioning gears 12 cooperate with the driving gear 7, so that the driving chain 6 at this location is in a "J" shape. Therefore, for the driving gear 7, the arc length of the arc-shaped working part on its outer edge exceeds the semicircular arc length, so that the contact area between the driving gear 7 and the driving chain 6 is greatly guaranteed, so that the interaction force between the driving gear 7 and the driving chain 6 is larger and more, so it provides a good foundation for power output.

[0043] like Figure 1 and Figure 4 As shown, in this embodiment, a boom seat 13 is provided on the sliding seat 2, and a plurality of working devices are movably provided on the boom seat 13. Further, the plurality of working devices include a rock drilling arm located at at least one side of the vehicle body 1, and a hanging basket arm located in the middle of the vehicle body 1. In this embodiment, the working device includes a left working device 14, a middle working device 15 and a right working device 16 arranged side by side in the width direction of the vehicle body 1. The three working devices can be movably arranged on the boom seat 13 to ensure that the working device can be displaced at least in the height direction to meet the actual rock drilling needs. The left working device 14, the middle working device 15 and the right working device 16 can be equipped with different rock drilling tools to meet specific construction requirements. In some embodiments, one of the working devices can be provided with an operating platform for construction personnel to perform construction processing at close range. At this time, the preferred position of the operating platform is the middle working device 15, which can meet the requirements of close-range construction processing on both sides. Of course, it is known that, in general, the rock drilling tools and / or the operating platform are arranged at the end of the corresponding working device, that is, the end away from the boom seat 13. Specifically, in this embodiment, the left working device 14 and the right working device 16 are both configured as rock drilling arms, and the middle working device 15 is configured as a hanging basket arm. Therefore, in the actual operation process, the left working device 14 and the right working device 16 can drill holes for the support surfaces on the corresponding sides, and the middle working device 15 can also be used to load explosives for the left working device 14 and the right working device 16 on both sides, thereby ensuring construction efficiency.

[0044] Therefore, it can be known that, in this embodiment, the arm support seat 13 can be moved forward and backward on the chassis 5. When the trolley is driving, the arm support seat 13 can be slid to a position close to the front of the vehicle body 1, so as to reduce the length of the entire vehicle, reduce the driving difficulty, optimize the load of the front and rear axles, and increase the life of the front and rear axles.

[0045] In some other technical solutions of this embodiment, in addition to being configured as a rock drilling arm, the working device can also be configured as other tunnel construction equipment, such as an arch transport device, a concrete spraying device, a grouting device, etc.

[0046] like Figure 1 As shown, in this embodiment, the front end of the vehicle body 1 is provided with a first mounting portion and a second mounting portion, and the first mounting portion and the second mounting portion are staggered up and down; the first mounting portion is provided with a reel 17, and the second mounting portion is provided with a reel 18. Among the reels 17 and 18, one is used for winding cables, and the other is used for winding water pipes. The cables and water pipes are usually used for rock drilling and connecting the trolley to the mains. In different operation scenarios, the two are not necessarily used at the same time. Therefore, when they are respectively wound on the reel 17 and the reel 18, they can be selected and used according to actual conditions. Since the first mounting portion and the second mounting portion are staggered up and down, the space on the trolley is also reasonably used, and the volume of the whole vehicle is effectively reduced.

[0047] In order to obtain sufficient driving vision during the movement of the trolley and ensure driving safety, the cockpit 3 is arranged on the sliding seat 2 in a liftable manner. At the same time, in order to lower the height of the entire vehicle when the trolley is traveling and protect the construction workers during operation, a liftable roof 22 is provided on the cockpit 3. It should be noted that the above-mentioned driver and construction worker can be the same person, or two or more people. Furthermore, in this embodiment, the cockpit 3 is arranged laterally, so that it is convenient for the driver to observe from front to back, thereby facilitating the safe forward or reverse movement of the vehicle.

[0048] like Figure 3 As shown, in this embodiment, the mechanism that enables the cockpit 3 to be raised and lowered and the mechanism that enables the ceiling 22 to be raised and lowered can be the same or different. Generally, a gear rack mechanism, a cylinder mechanism, a linear motion mechanism, etc. can be used. This embodiment uses a cylinder mechanism for illustration. Taking the cockpit 3 as an example, the cylinder mechanism includes an outer cylinder 19, an inner cylinder 20, and a lifting cylinder 21. The outer cylinder 19 is fixedly connected to the cockpit 3, and the inner cylinder 20 is fixedly installed on the sliding seat 2. The inner cylinder 20 can be inserted into the outer cylinder 19 and has a certain gap with the outer cylinder 19. The lifting cylinder 21 is used to drive the outer cylinder 19 to move, so that the outer cylinder 19 can move up and down relative to the inner cylinder 20 under the action of the lifting cylinder 21, so that the cockpit 3 can be raised and lowered relative to the sliding seat 2.

[0049] Therefore, this embodiment reduces the difficulty of driving the trolley in the tunnel, effectively reduces the wear of the front and rear axles, extends the service life of the front and rear axles, and when the working device faces step construction, avoids the risk of interference between the working device and the steps, effectively improving construction efficiency.

[0050] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
