Description

Sleeper concrete spreader

Technical Field

The application relates to the technical field of high-speed rail production equipment, in particular to a sleeper concrete spreader.

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. Because the high-speed rail has high requirements on the flatness of the rail and good consistency needs to be kept between every two sleepers, the high-speed rail sleepers need to ensure the consistency of a mold and strictly control the filling amount of concrete during production.

In order to ensure consistency among sleepers, the sleepers can be produced in a mode of quantitatively weighing the mass of concrete, so that the amount of concrete poured into each mould is kept consistent. For example, the concrete material to be poured can be divided into multiple parts, the parts are respectively placed on a weighing device to be weighed, and the parts are respectively poured into the mould when the weights of the multiple parts of concrete tend to be consistent. The method is complex in operation, needs more manual operations and is low in efficiency, and because the concrete is a mixed material of sand, cement and water, the proportions of the sand, the cement and the water contained in different parts of the concrete are possibly different in the weighing process, so that the shape of the concrete in the solidification process is different, the method is time-consuming and labor-consuming, and the better consistency effect cannot be achieved.

In actual production, the concrete can be stirred and poured successively by special pouring equipment. A typical filling apparatus includes a mix hopper and a filling opening provided at the bottom of the mix hopper. Stirring components such as stirring blades or stirring rods are arranged in the stirring hopper, and the stirring components can be used for continuously stirring the concrete in the stirring hopper under the driving of a motor, so that the proportions of concrete, gravel, cement and water in the hopper are kept consistent. The filling opening can be provided with valve components such as an electromagnetic valve, an electric telescopic baffle and the like so as to control the opening and closing of the filling opening. In practical application, the mould is placed on the weighing device, the pouring device is moved to the position above the mould, and the controller opens the valve component to enable the concrete to fall into the mould. The weighing device continuously acquires weight information of the falling concrete and sends the acquired weight information to the controller, and when the falling concrete amount reaches a set value, the valve part is closed, so that the concrete amount in each mould tends to be consistent.

Therefore, although the pouring equipment can improve the pouring efficiency and maintain partial consistency, the weighing equipment usually needs to keep the materials placed on the weighing equipment in a static state to obtain a better weighing effect because the mould needs to be placed on the weighing equipment in the pouring process of the pouring equipment. Therefore, the weighing equipment can not be directly integrated on the conveying line of the mould, and the mould needs to be carried to the weighing equipment deliberately, so that the filling equipment can not be well adapted to the production line with higher automation degree. In addition, as the concrete often contains gravels with larger particles, the concrete is easy to have large gravels to block the valve component when falling, so that the valve component is not closed timely or tightly, the concrete continuously falls, and the consistency of the concrete amount in each mould is influenced.

Through two cowl 24, can realize more rapidly the adjustment to discharge gate 23 open area, improve the efficiency of unloading. In addition, when the arc-shaped baffle plate 24 on one side is blocked by sand and stones, the discharge hole 23 can be closed by adjusting the arc-shaped baffle plate 24 on the other side.

As shown in fig. 3, the distributing mechanism 3 includes a frame 31 spanning above the die line 1, and a plurality of transfer units 32 disposed on the frame 31. The frame 31 may be an arch structure to span multiple mold conveying lines 1, and simultaneously implement a pouring process for multiple sleeper molds 11. A weighing sensor 33 is arranged between the transfer component 32 and the rack 31; the bottom of transfer subassembly 32 is equipped with cloth material mouth 34, be equipped with valve part 35 on the cloth material mouth 34 in order to control the opening and closing of cloth material mouth 34.

In practical application, the transfer assembly 32 may include a transfer concrete bin having a funnel-shaped structure, the concrete material falling through the discharge port 23 may enter the concrete bin, and the weight of the falling concrete may be weighed by the transfer assembly 32 due to the weighing sensor 33 disposed at the position of the transfer assembly 32. After weighing, the concrete material can be dropped into the sleeper mold 11 by opening the material distribution port 34.

In the technical scheme that this application provided, load cell 33, cowl 24 and valve member 35 are connected respectively the controller, through the concrete material of discharge gate 23 whereabouts gets into in transfer subassembly 32, by load cell 33 accomplishes the ration and weighs, the rethread cloth mouth 34 fills in the sleeper mould 11. The application provides sleeper concrete spreader's actual work process promptly does:

after the material transporting vehicle 22 receives the concrete material, the motor works to enable the material transporting vehicle 22 to run along the material transporting track 21, and after the material transporting vehicle 22 runs to a specified position, namely above the material distributing mechanism 3, the material transporting vehicle 22 stops moving. The hydraulic cylinder on the material transporting vehicle 22 is controlled to work, and the movable rod is retracted. The moving rod drives the arc-shaped baffle 24 to open, so that the concrete raw material falls into the storage hopper 321 of the distributing mechanism 3. The weighing sensor 33 feeds back weight data in real time, so that when the controller judges that the weighing reaches a certain numerical value, a stop signal is fed back, the first hydraulic cylinder is controlled to extend the moving rod, and the discharge hole 23 of the material transporting vehicle 22 is closed. After that, the material transporting vehicle 22 can move to the upper side of the next material distributing mechanism 3, and the above actions are repeated to complete the material replenishing operation of another material distributing mechanism 3.

In some embodiments of the present disclosure, the transfer assembly 32 includes a storage hopper 321 and a plurality of dispensing hoppers 322 disposed on the frame 31; the plurality of distributing hoppers 322 are arranged below the storage hopper 321; the weighing sensor 33 is arranged between the storage hopper 321 and the rack 31; the weighing sensor 33 is also arranged between the material distribution hopper 322 and the frame 31. In practical applications, the concrete material falling from the discharge port 23 will fall into the storage hopper 321, and the weight of the material is primarily measured by the weighing sensor 33 on the storage hopper 321. And then enter each distribution hopper 322, are further precisely weighed by each distribution hopper 322, and finally fall into the pouring cavity on the sleeper mold 11 corresponding to each distribution hopper 322.

In order to enable concrete materials to be poured into each pouring cavity respectively, the number of the distributing hoppers 322 is the same as that of the pouring cavities on the sleeper mold 11; alternatively, the number of the distribution hoppers 322 is a multiple of the number of the pouring cavities on the sleeper mold 11.

For example, when two filling cavities are included in one sleeper mold 11, two sub-hoppers 322 may be disposed in the transferring assembly 32, and the two sub-hoppers 322 correspond to the two filling cavities, respectively, so as to fill the two filling cavities in one filling process. For another example, when two injection cavities are included in one sleeper mold 11, four material distribution hoppers 322 may be disposed in the transferring assembly 32, and the four material distribution hoppers 322 respectively correspond to the four injection cavities in total on the two sleeper molds 11, so that the injection process of the two sleeper molds 11 is completed simultaneously in one injection process, and the injection efficiency is improved.

In practical applications, since one sub-hopper 322 corresponds to one filling cavity, the amount of concrete material falling into each sub-hopper 322 is the amount of concrete filled into the filling cavity. Thus, the distributing hopper 322 needs to pass through the distributing port 34 and the valve member 35 independently of each other to control the amount of concrete falling therein.

After the concrete material amount of each distributing hopper 322 meets the preset requirement, the distributing openings 34 on the distributing hoppers 322 can be opened simultaneously so that the concrete materials fall into the filling cavity, so that the distributing openings 34 of the distributing hoppers 322 do not need to be controlled independently, and the filling efficiency can be improved by opening and closing simultaneously. In addition, the material distributing openings 34 of the distributing hoppers 322 are opened simultaneously, so that concrete materials falling into the sleeper mold 11 can tend to be balanced, the phenomenon that the position of the sleeper mold 11 is changed due to impact in the blanking moment is avoided, and the pouring quality is improved.

Further, in order to open and close the material distribution port 34, the valve member 35 includes a flat plate, and a second hydraulic cylinder connected to the flat plate; the area of the flat baffle is larger than the opening area of the material distribution port 34; the second hydraulic cylinder is arranged on the frame 31, and the flat baffle is connected with a piston of the second hydraulic cylinder through a connecting rod. The hydraulic cylinder can drive the connecting rod to move horizontally, so that the flat baffle is controlled to block or dredge the material distribution opening 34, and the material distribution opening 34 is opened and closed. In this embodiment, the flat baffle is used to control the opening and closing of the material distribution port 34, so that the overall height of the material distribution mechanism 3 can be further reduced on the basis of satisfying the control action, and the production line structure is more compact.

It can be seen that, based on the material distribution mechanism 3, in practical application, the material distribution can be performed in the following manner: the motor on the distributing mechanism 3 works to drive the distributing mechanism 3 to move on the rack 31 and respectively move to the positions above the two sleeper moulds 11 in the second row and the first row of the sleeper moulds 11. The second hydraulic cylinder is controlled to retract the connecting rod, the flat baffle is opened to replenish the material of the material distribution hopper 322, the weighing sensor 33 feeds back a signal to the controller after weighing to a preset value, and the controller controls the connecting rod of the second hydraulic cylinder to extend out to close the material distribution opening 34 of the material storage hopper 321.

The second cylinder corresponding to the time division hopper 322 acts to open the material distribution port 34, so as to accurately distribute the material to the sleeper mold 11, and after the material distribution is completed, the second cylinder acts again to close the material distribution port 34, so that one-time material distribution is completed. The material distributing mechanism 3 moves forwards to the position above the third row of moulds and the fourth row of moulds again, and the above actions are repeated to complete material distribution, so that the material distributing work of the whole group of moulds is completed.

In some embodiments of the present application, as shown in fig. 4, the sleeper concrete spreader further includes a stirring member 4; the stirring component 4 comprises a stirring blade and a stirring motor connected with the stirring blade; the stirring blades are arranged in the material conveying vehicle 22 and/or the transfer assembly 32; the stirring motor is arranged on the outer wall of the material conveying vehicle 22 and/or the transfer assembly 32.
