Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings.
The utility model relates to an to the improvement of box culvert loop wheel machine, box culvert loop wheel machine is used for the handling box culvert and installs the box culvert in the tunnel. The box culvert hoisting mechanism after the improvement can be fine be fixed in the box culvert on bearing the support, has avoided rocking of hoisting in-process box culvert, has guaranteed the stability of box culvert hoist and mount, has stopped the potential safety hazard when improving the precision of follow-up installation.
Specifically, a box culvert hoisting mechanism in this embodiment includes the mechanism body (not shown in the figure) that can remove along the extending direction in tunnel, locates the lifting components on the mechanism body. The mechanism body is a trolley capable of moving along a tunnel and is used for driving the hoisting assembly to move along the tunnel and sequentially install the box culvert.
Referring to fig. 1-2, the hoisting assembly comprises a bearing support 1 which is connected to the mechanism body in a turnover manner and used for bearing the box culvert, and limiting parts 2 arranged on the left side and the right side of the bearing support 1. Wherein the box culvert is of a hollow structure with an upper opening and a lower opening, the box culvert is placed on the conveying vehicle before being lifted, and the width of the box culvert is larger than that of the vehicle. During the handling, locating part 2 can the complex penetrate the lower extreme opening of box culvert and butt in the inside wall of box culvert from delivery wagon both sides lower part. The setting through locating part 2 can be fine carry on spacingly to the box culvert lateral wall, has avoided the box culvert to rock.
Further, foretell lifting by crane subassembly is still including locating on bearing support 1 and compressing tightly 3 with the corresponding setting of locating part 2, compresses tightly 3 and can be along the direction motion that is close to locating part 2 and support the box culvert to press on locating part 2, or, move and break away from the box culvert along the direction of keeping away from locating part 2. The pressing member 3 is here a hydraulic jack, the piston rod of which is movable in a direction towards or away from the limiting member 2. The lateral wall of the box culvert is pressed against the limiting part 2 through the pressing part 3, so that the limiting effect is further guaranteed, and the box culvert can be firmly fixed on the bearing support 1.
In this embodiment, the supporting bracket 1 includes a U-shaped bracket body 11 and a plurality of supporting portions 12 disposed on the inner peripheral side of the bracket body 11, and the box culvert can be supported on the plurality of supporting portions 12 in a matching manner. And the two limiting parts 2 are located on the two supporting parts 12 at one end of the bracket body 11 close to the mechanism body. Here, there are four supporting parts 12, and lie in four tip of support body 11 respectively, and during the handling, each tip of box culvert erects respectively on these four supporting parts 12, and locating part 2 lies in the one side that two supporting parts 12 that are close to the mechanism body are close to each other, and the lower extreme opening that can cooperate and penetrate the box culvert realizes spacingly.
Specifically, the limiting member 2 includes a first limiting rod 21, and a second limiting rod 22 connected to an end of the first limiting rod 21 and extending along a length direction perpendicular to the first limiting rod 21, wherein the first limiting rod 21 can be engaged with the box culvert to penetrate the box culvert, and the second limiting rod 22 can be engaged with the box culvert to abut against an inner side wall of the box culvert. One end of the second limiting rod 22 close to the box culvert is provided with a butt joint surface matched with the inner side wall of the box culvert. Here, since the two ends of the inner side wall of the box culvert are provided with the chamfers, the abutting surfaces are inclined surfaces matched with the chamfers.
The hoisting mechanism further comprises a plurality of lifting pieces 4 which can be respectively matched with each end of the bearing support 1 to drive the bearing support to lift, wherein each lifting piece 4 comprises a driving piece (not shown in the figure) arranged on the mechanism body, a pulley 41 which can rotate around the axis direction of the lifting piece and can rotate around the end of the bearing support and is arranged on the bearing support 1, and a driving rope 42 connected between the driving piece and the pulley 41. The driving cable 42 is a steel cable, the driving element comprises a steel cable cylinder for winding the steel cable and a motor for driving the steel cable cylinder to rotate, the steel cable cylinder is driven to rotate by the motor, and the steel cable cylinder drives the pulley to lift through winding and unwinding the steel cable, so that the end part of the bearing support 1 is hoisted and lifted.
In this embodiment, the plurality of lifting members 4 can operate independently and synchronously in cooperation with each other, and only the corresponding motor needs to be turned on as required during operation. Each lifting piece 4 can be independently controlled, so that the flexibility of box culvert lifting is improved, and the aim of flexibly adjusting the posture of the box culvert is fulfilled.
The hoisting mechanism further comprises a limit sensor 5 which is arranged corresponding to the lifting piece 4 and is respectively positioned below each pulley 41, and the limit sensor 5 is an infrared sensor. Because the box culvert needs to be turned when the box culvert is installed, the heights of the front end and the rear end of the bearing support 1 during lifting are inconsistent, and the pulley 41 needs to rotate correspondingly around the end part of the bearing support 1 to turn over. The limiting sensor 5 is used for limiting the excessive overturning of the pulley 41, so that the box culvert can operate within a designed angle range in the overturning process, and the unstable gravity center caused by the overlarge overturning angle is prevented. Specifically, when the pulley 41 is turned over excessively to reach the limit sensor 5, the limit sensor 5 senses the pulley 41 and sends an alarm signal, and the controller can control the motor to stop driving. The controller here is a conventional control system.
The following specifically explains the working process of this embodiment: when the work begins, the mechanism body removes to the box culvert other, bears support 1 this moment and holds in the palm the box culvert, and locating part 2 penetrates the lower extreme opening of box culvert and supports the box culvert inside wall, compresses tightly 3 functions and compresses tightly the box culvert afterwards, and the lifting 4 that bears each tip of support 1 at last mutually supports the lifting upset that realizes the box culvert, accomplishes the installation of box culvert.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
