Description

Technical Field

[0001] The utility model mainly relates to the technical field of tunnel construction, and particularly relates to a tunnel steel cage operation device with a suspension mechanism. Background Art

[0002] Secondary lining (abbreviated as "second lining") is a commonly used term in tunnel engineering construction. It refers to the reinforced concrete lining constructed on the inner side of the primary support, aiming to jointly form a composite lining with the primary support to achieve the effect of strengthening the support and thus meet the requirements of modern tunnel construction.

[0003] The secondary lining includes steel bar construction, that is, an arched steel cage adapted to the shape of the tunnel inner wall is formed by binding. The steel cage includes an inner and an outer layer of steel bar meshes. The steel bar mesh is formed by the cross of ring steel bars and transverse steel bars in a grid pattern. The two ends of the ring steel bars need to be connected to the inverted arch steel bars embedded on both sides of the tunnel bottom through steel sleeves. After the steel sleeves are sleeved on the ends of the ring steel bars and the inverted arch steel bars, a hydraulic clamp needs to be used to apply pressure to the steel sleeves to cause them to deform, so as to form a stable connection with the ring steel bars and the inverted arch steel bars.

[0004] Since the tunnel steel cage operation device in the prior art (such as the technical solution disclosed in the Chinese patent application document with the application publication number: CN 115163139 A and the invention name "Tunnel Steel Cage Operation Device and Tunnel Steel Cage Construction Method") is not equipped with a suspension mechanism, the operator can only move the hydraulic clamp by hand, and the hydraulic clamp is relatively heavy, so a large amount of physical strength will be consumed. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a tunnel steel cage operation device with a suspension mechanism.

[0006] To solve the above technical problem, the utility model adopts the following technical solutions:

[0007] A tunnel steel cage operation device with a suspension mechanism includes a carrier frame, a pair of arc tracks fixed on the outer side of the carrier frame, a drawing device arranged on the arc tracks and used to drive the steel bars to be arranged along the tunnel length direction to be arranged along the tunnel circumferential direction, and also includes a suspension mechanism; the suspension mechanism includes a chute fixed on the drawing device along the tunnel length direction, and a slider slidably installed in the chute, and a hydraulic clamp is detachably suspended on the slider.

[0008] As a further improvement of the above technical solution:

[0009] Blocking members for preventing the slider from disengaging are arranged at both ends of the chute.

[0010] A roller is installed on the slider, and the roller is in rolling contact with the chute.

[0011] Two sliders are installed in each chute in a rolling manner.

[0012] The slider is connected to the hydraulic pliers through a balancer; a detachable connection is provided between the balancer and the slider and between the balancer and the hydraulic pliers.

[0013] There are two sets of the suspension mechanisms. The chute of one set of the suspension mechanisms is fixed to the bottom surface of the drawing device, and the chute of the other set of the suspension mechanisms is fixed to the top surface of the drawing device.

[0014] The tunnel steel reinforcement cage working equipment further includes a high and low pressure pumping station fixed on the bearing frame, and the high pressure output end of the high and low pressure pumping station is connected to the hydraulic pliers.

[0015] Compared with the prior art, the advantages of the present utility model are as follows:

[0016] By adding a suspension mechanism, which includes a chute fixed on the drawing device along the length direction of the tunnel, a slider is slidably installed in the chute, and the hydraulic pliers are connected to the slider, and it can move in a suspended manner along the length direction of the chute (i.e., along the length direction of the tunnel) following the slider, so as to be able to replace the way that the operator moves the hydraulic pliers by hand in the prior art, and thus can save manpower.

Detailed Description of the Embodiment

[0021] The following will further describe the present utility model in detail with reference to the drawings of the specification and specific embodiments.

[0022] Embodiment

[0023] As Figures 1 to 3As shown in the figure, the tunnel steel cage working equipment with a suspension mechanism in this embodiment includes a carrier frame 1, a pair of arc-shaped tracks 2 fixed on the outer side of the carrier frame 1, and a drawing device 3 arranged on the arc-shaped tracks 2 and used to drive the steel bars to change from being arranged along the tunnel length direction to being arranged along the tunnel circumferential direction. It also includes a suspension mechanism 4; the suspension mechanism 4 includes a chute 41 fixed on the drawing device 3 along the tunnel length direction, and a slider 42 slidably installed in the chute 41. A hydraulic clamp 5 is detachably suspended on the slider 42. The carrier frame 1 is set as an arch-shaped frame, which includes four U-shaped frames 11 arranged at intervals along the tunnel length direction, and each U-shaped frame 11 is connected into a whole by a beam 12 arranged along the tunnel length direction. One arc-shaped track 2 is fixed at the front end of the carrier frame 1 along the tunnel length direction, and the other arc-shaped track 2 is fixed at the rear end of the carrier frame 1 along the tunnel length direction. A belt (not shown in the attached drawing) is arranged on the arc-shaped track 2, and the belt is connected to the drawing device 3 arranged along the tunnel length direction. The belt can reciprocate along the arc-shaped track 2 under the drive of an external driver, so as to drive the drawing device 3 to move synchronously along the arc-shaped track 2. The structures, assembly relationships and working principles of the carrier frame 1, the arc-shaped track 2 and the drawing device 3 are all prior arts and will not be elaborated here. The difference between this embodiment and the prior art is mainly reflected in that a suspension mechanism 4 is added, which includes a chute 41 fixed on the drawing device 3 along the tunnel length direction. A slider 42 is slidably installed in the chute 41, and the hydraulic clamp 5 is connected to the slider 42, and it can move in a suspended manner along the length direction of the chute 41 (i.e., along the tunnel length direction) following the slider 42, so as to be able to replace the way that the operator moves the hydraulic clamp 5 by hand in the prior art, and thus can save manpower.

[0024] In this embodiment, stoppers (not shown in the drawings) for preventing the slider 42 from disengaging are provided at both ends of the chute 41. The stopper can be set as a bolt or a baffle welded to the end of the chute 41. By providing stoppers at the ends of the chute 41, when the slider 42 slides to the end of the chute 41, the slider 42 cannot continue to move under the blocking action of the stopper, thus effectively avoiding the situation where the slider 42 disengages from the end of the chute 41 and causing the hydraulic pliers 5 to fall. Further, rollers 421 are installed on the slider 42, and the rollers 421 are in rolling contact with the chute 41. By providing rollers 421 on the slider 42, the contact between the slider 42 and the chute 41 is changed from frictional contact to rolling contact. When the friction is reduced, the wear between the slider 42 and the chute 41 can be delayed to a certain extent, thereby extending the service life of the equipment. Furthermore, two sliders 42 are installed in each chute 41 in a rolling manner. Each slider 42 can be connected to a hydraulic pliers 5, so that two operators can perform tightening operations simultaneously, improving work efficiency. Furthermore, the slider 42 and the hydraulic pliers 5 are connected by a balancer 6; both the connection between the balancer 6 and the slider 42 and the connection between the balancer 6 and the hydraulic pliers 5 are set as detachable connections. The balancer 6 is a commercially available product, which can make the hydraulic pliers 5 hover at any height, thus facilitating the operator to adjust the position of the hydraulic pliers 5 according to the actual situation at the construction site.

[0025] In this embodiment, there are two sets of suspension mechanisms 4. The chute 41 of one set of suspension mechanisms 4 is fixed to the bottom surface of the drawing device 3, and the chute 41 of the other set of suspension mechanisms 4 is fixed to the top surface of the drawing device 3. Since the drawing device 3 moves along the arc-shaped track 2 driven by the belt, when the drawing device 3 moves from one side of the tunnel to the other side, its top surface and bottom surface will be inverted. By providing two sets of suspension mechanisms 4, and fixing the chute 41 of one set of suspension mechanisms 4 to the bottom surface of the drawing device 3 and the chute 41 of the other set of suspension mechanisms 4 to the top surface of the drawing device 3, so that no matter which side of the tunnel the drawing device 3 is located on, there is a set of suspension mechanisms 4 located below the drawing device 3, thus facilitating the installation of the hydraulic pliers 5 on this suspension mechanism 4.

[0026] In this embodiment, the tunnel steel cage working equipment further includes a high and low pressure pumping station 7 fixed on the carrier 1, and the high pressure output end of the high and low pressure pumping station 7 is connected to the hydraulic pliers 5. The operation of the tunnel steel cage working equipment requires the pumping station to provide kinetic energy, and the operation of the hydraulic pliers 5 also requires the pumping station to provide kinetic energy, but the required hydraulic pressures of the two are different. By providing a high and low pressure pumping station 7, connecting its low pressure output end to the low pressure equipment to provide kinetic energy for the low pressure equipment, and connecting its high pressure output end to the hydraulic pliers 5 to provide kinetic energy for the hydraulic pliers 5, it is possible to realize that one pumping station provides kinetic energy for actuators with different pressure requirements at the same time.

Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model by using the technical content disclosed above without departing from the scope of the technical solution of the present utility model, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall fall within the scope of protection of the technical solution of the present utility model.
