Description

Sleeper truss assembly equipment

Technical Field

The application relates to the technical field of sleeper production, in particular to sleeper truss assembling equipment.

Background

The high-speed rail sleeper is a concrete sleeper block paved below a high-speed rail steel rail to support the high-speed rail steel rail, buffer the pressure on the steel rail and maintain the flatness of the surface of the steel rail. The high-speed rail sleeper is manufactured by placing a truss and filling concrete in a mould, and cooling and forming the high-speed rail sleeper. The concrete material poured at the two ends of the truss needs to have enough thickness and strength, so that the truss and the matched stirrups need to be preset in the mould before the concrete is poured so as to have a supporting function after the concrete material is solidified.

Because the requirement of the high-speed rail on the flatness is higher than that of a common railway, the thickness of concrete at two ends of a truss of the high-speed rail sleeper needs to be kept consistent, and an important factor influencing the thickness of the concrete is the distance between a stirrup and the truss. In order to maintain the distance between the stirrup and the truss, a plurality of thin steel wires are generally bound between the stirrup and the truss, and the length maintained by the bound thin steel wires is the distance between the stirrup and the truss. However, the production mode needs to artificially bind the thin steel wires, and the production efficiency is low. And because the stirrup plane and the truss plane need to be parallel to each other in the binding process, the operation difficulty is high, and if the binding force of each thin steel wire is not uniform, the stirrup plane and the truss plane are easy to lose the parallel relation.

In order to improve the above problem, hooks with uniform specification and shape can be generated in advance, generally, the hooks are formed by bending thin steel wires at two ends respectively, and the two ends of the hooks are hung on the truss and the stirrups respectively, so that mutual installation between the truss and the stirrups is realized, and the parallel relationship between the stirrup plane and the truss plane can be maintained by the gravity action of the stirrups.

The mode of assembling the hook can easily cause the hook assembly failure because the stirrup swings in the moving process and the stirrup is separated from the bottom end of the hook. Meanwhile, as a plurality of hooks are often required to be installed between the stirrups and the truss, and after one hook is assembled, the other hooks cannot complete the assembling mode, a control action program needs to be rewritten, or a plurality of clamping devices simultaneously act, even if the mode has high error rate.

The embodiments described in the following examples do not represent all embodiments consistent with the present application. But merely as exemplifications of systems and methods consistent with certain aspects of the application, as recited in the claims.

In the technical scheme provided by the application, the truss is formed by welding three longitudinal steel bars and reciprocating rotary bent steel bars between two of the three longitudinal steel bars, and the cross section of the truss is integrally V-shaped. In practical application, a plurality of hooks need to be hung on the middle longitudinal steel bar of the V-shaped truss so as to connect the stirrups through the hooks. The hook is formed by bending and shaping a thin steel wire, the two ends of the hook are provided with hooks, and the middle part of the hook is of a straight structure. In practical application, the plane of the truss and the plane of the stirrup need to be kept parallel, so that the specification of the hook needs to be as uniform as possible. The stirrup is formed by bending and shaping a reinforcing steel bar and is of a rectangular structure. The hooks are required to be installed on two long edges of the stirrup to realize the connection with the longitudinal steel bars in the middle of the truss, namely, each edge of the stirrup corresponds to one truss.

In order to realize the installation between sleeper truss, stirrup and the couple three, this application provides a sleeper truss rigging equipment. Referring to fig. 1, a structural diagram of a sleeper truss assembling apparatus is shown. As shown in fig. 1, the sleeper truss assembling equipment provided by the present application includes a truss conveying line 1 and a stirrup conveying line 4, and further includes a truss overturning device 2 spanning above the truss conveying line 1, and a hook device 3 spanning above the stirrup conveying line 4. In addition, the sleeper truss assembly equipment that this application provided still includes the support frame that is used for supporting each part, and fixes each part. According to the technical scheme, the trusses are usually stacked together after welding is completed, so that transportation is facilitated. The truss conveying line 1 may include two parallel conveying chains, and in practical production, a certain number of trusses stacked together are taken and transversely placed between the two conveying chains. The motor is started to work, the transmission chain is driven to move, and the transmission chain drives the stacked trusses to be transported to the truss overturning device 2.

Further, as shown in fig. 2, the truss conveying line 1 is further provided with a sampling inspection platform 11 and a frame taking mechanism 12; the sampling inspection platform 11 and the rack taking mechanism 12 are perpendicular to the truss conveying direction of the truss conveying line 1; the rack taking mechanism 12 is a lifting component arranged below the truss conveying line 1, so that the truss on the truss conveying line 1 is moved to the sampling inspection platform 11 through the rack taking mechanism 12. In practical application, a worker can perform sampling inspection on the trusses on the truss conveying line 1 through the sampling inspection platform 11 and the frame taking mechanism 12, and find deformed or poor trusses in time.

Under the normal working state, the frame taking mechanism 12 is contracted below the conveying chain of the truss conveying line 1, and the truss conveying line 1 operates normally to convey the truss to the truss overturning device 2. When the sampling inspection is needed, the frame taking mechanism 12 is started to work, and the height of the frame taking mechanism is increased, so that the truss is jacked up, and the truss and the conveying chain are separated from each other. And then, a plurality of rollers are arranged on the frame taking mechanism 12, and the rollers start to rotate after the truss is separated from the conveying chain, so that the truss is moved along the truss conveying direction perpendicular to the truss conveying line 1, namely, the truss is moved towards the sampling inspection platform 11. Therefore, the truss is moved from the truss conveying line 1 to the sampling inspection platform 11, and sampling inspection operation is carried out.

In the technical scheme that this application provided, because the truss wholly presents the triangular prism shape, stack each other between stability and a plurality of trusses in order to guarantee the transportation, the truss will be placed for the shape of inversion V-arrangement usually. Therefore, the truss turning device 2 can complete two processes, one is to turn the truss placed in the inverted V shape into a V-shaped placing shape; and the other step is to separate the turned trusses one by one so as to finish the assembly respectively.

The turnover mechanism 21 may be two V-shaped clamps disposed at two sides of the truss conveyor line 1, that is, after the truss reaches the truss turnover device 2, the end of the truss may be clamped by the V-shaped clamps at the two sides, and then the truss is turned over under the driving of the turnover motor 22, so that the truss placed in an inverted V shape is rotated 180 degrees, and a V-shaped placement posture is presented.

The trusses placed on the truss conveying line 1 are stacked, and the number of the trusses stacked at a time is not fixed. Therefore, in some embodiments of the present application, the turnover mechanism 21 is provided with a carrier sheet, and the V-shaped clamp in the turnover mechanism 21 can also be slidably connected to the support frame to adjust the distance between the carrier sheet and the V-shaped clamp. In the non-overturned state, the truss is in an inverted V shape from the truss conveying line 1 and stops on the bearing plate, and the V-shaped clamp is controlled by a motor or a hydraulic cylinder to move downwards until the stacked trusses are pressed together. At this time, the turnover motor 22 is started again, so that the turnover mechanism 21 and the trusses are turned over for 180 degrees to be in the V-shaped posture. Through the structure, the structure is suitable for stacking forms of more trusses with different quantities, the stacked trusses can be prevented from being loose and falling during overturning, and the overturning quality is improved.

After the truss is turned over, the carrying mechanism 23 located above the turning mechanism 21 is started to work, and the turned truss is grabbed through the manipulator. In practical applications, the handling mechanism 23 may work in a process that after the turning is completed, the handling mechanism moves downward to reach the position of the first truss to be stacked, and the manipulator starts to close to clamp the truss. After the trusses are clamped, the carrying mechanism 23 is lifted to a preset height and then translates towards the commodity shelf 24 until the commodity shelf 24 is reached. And then moves downward to a pre-positioned position, and opens the manipulator to maintain the truss in a turned posture and place the truss on the shelf 24.

In practical application, after grabbing the truss on the rack 24 to a certain height, the truss hanger 31 moves towards the stirrup conveying line 4 and reaches the position right above the stirrup conveying line 4. And then moving downwards until the contact hoop reinforcement or the distance between the contact hoop reinforcement and the hoop reinforcement is smaller than the distance between the hooks at the two ends of the hook. At the same time, the hook holder 32 moves the hook in a direction close to the truss and the stirrups so that the stirrups and the longitudinal reinforcements in the middle of the truss enter between the two ends of the hook and are bent. At this time, the truss lifting appliance 31 moves upwards again, so that the longitudinal steel bars in the middle of the truss enter the hooks at the top, the truss lifting appliance 31 continues to move upwards to drive the truss and the hooks to move upwards together until the stirrups enter the hooks at the bottom of the hooks, and the assembly of the hooks is completed.

After the hook assembly is completed, the truss lifting tool 31 continues to move upward, and the stirrups can be separated from the stirrup conveying line 4 through the hooks. Finally, the assembled truss with stirrups is placed in a sleeper mould by a truss hanger 31 for subsequent concrete pouring.
