Description
Technical Field
[0001] This invention relates to pipe forming production equipment for concrete structure pipes, specifically a rapid demolding device for jacking pipe production. Background Technology
[0002] Currently, the existing production processes for concrete or reinforced concrete drainage pipes include: centrifugal process, suspension rolling process, radial extrusion process, and core mold vibration process; among them, the centrifugal process and suspension rolling process are horizontal production processes, while the radial extrusion process and core mold vibration process are vertical production processes.
[0003] Generally, there are two methods for separating the mold and the concrete pipe: a disassembly method, where the bolts on the outside of the mold are removed, the mold is disassembled, and then the mold and concrete are separated under external force; and a monolithic method, where the mold is separated from the concrete pipe. The monolithic method, to some extent, increases labor intensity and time costs, and excessive external force during separation may damage the formed concrete pipe. Therefore, we provide a rapid demolding device for pipe jacking production. Summary of the Invention
[0004] The purpose of this invention is to provide a rapid demolding device for pipe jacking production to solve the above-mentioned problems.
[0005] The present invention can be achieved through the following technical solution: a rapid demolding device for pipe jacking production, comprising a demolding worktable and a mold, wherein the demolding worktable is provided with an outer mold release point and an inner mold release point from left to right, the mold includes an outer mold and an inner mold, a frame for conveying the mold is provided above the demolding worktable, the frame is detachably connected to the top of the inner mold, an outer mold demolding rotary platform is provided at the outer mold release point, an oiling component is provided inside the outer mold demolding rotary platform, an inner mold demolding rotary platform is provided at the inner mold release point, and a clamping and transporting mechanism is installed on the right side of the demolding worktable at a position corresponding to the inner mold release point.
[0006] A further technical improvement of the present invention is that: a concrete pipe is sleeved on the outside of the inner mold, and an outer mold is sleeved on the outside of the concrete pipe. The bottom edge of the inner mold protrudes outward and is embedded in the outer mold. A connecting groove is provided on the top of the inner mold and the connecting groove is threaded inside.
[0007] A further technical improvement of the present invention is that: a support column is connected inside the frame via gear transmission, the bottom of the support column is threaded, and the bottom of the support column is set in the connecting groove and threadedly connected to the inner mold.
[0008] A further technical improvement of the present invention is that: the outer mold rotation platform includes an outer mold rotation track support and an outer mold rotation worktable. The outer mold rotation worktable has a hole adapted to the outer mold on the right side. The top of the outer mold rotation track support is provided with two sets of lifting cylinders. The two sets of lifting cylinders are respectively located below the hole and below the point where the outer mold is disengaged. The movable end of the lifting cylinder is provided with an adsorption plate for adsorbing and fixing the outer mold.
[0009] The outer mold rotary track is symmetrically arranged inside the outer mold rotary track support base for transporting the outer mold, and the outer mold rotary track is provided with limit protrusions.
[0010] A further technical improvement of the present invention is that: the oiling assembly includes a lifting support seat 1 located at the bottom center of the outer mold rotary track support seat, and an oiling support platform is installed on the upper telescopic part of the lifting support seat 1, and an annular protruding oiling part is provided on the outer surface of the oiling support platform.
[0011] A further technical improvement of the present invention is that: the inner mold demolding rotary platform includes an inner mold rotary track and a demolding support platform, the rotary track includes two symmetrically arranged transmission belts, and multiple limiting baffles are evenly spaced at corresponding positions on opposite sides of the two transmission belts;
[0012] The demolding support platform is parallel to the upper surface of the demolding worktable. A second lifting support seat is provided at the bottom of the demolding support platform, and the second lifting support seat drives the demolding support platform to rotate and rise.
[0013] A further technical improvement of the present invention is that: the clamping and transporting mechanism is provided with translation slide rails on both sides, and a support seat that can move on the translation slide rail is provided on the translation slide rail; a telescopic cylinder is provided on the inner side of the support seat, and the end of the telescopic cylinder is fixedly connected to the clamping plate.
[0014] A further technical improvement of the present invention is that: the surface of the demolding worktable is symmetrically provided with sliding grooves, and the demolding support table is correspondingly provided with limiting sliding grooves and limiting slots. The two sliding grooves are connected to the limiting sliding grooves and limiting slots, and the protrusions provided at the bottom of the inner mold cooperate with them.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. Using a lifting demolding mechanism and an outer mold track, the demolded outer mold is moved from the bottom to the outer mold rotation track, and then lifted back to the concrete placement position. As the outer mold separates from the concrete pipe downwards, the oiling part on the outside of the oiling support platform used to support the inner mold cleans and oils the inside of the outer mold as it descends. After the top of the outer mold descends to the worktable, the inner mold moves to the right to the inner mold separation point, and the oiling support platform moves down to clean and oil the inner wall of the outer mold. The demolding and cleaning / oiling of the outer mold are carried out in a continuous process, reducing both operation and operation time.
[0017] 2. When the lifting and demolding mechanism detaches from the outer mold, the concrete pipe that detached from the outer mold and the inner mold also detach from the inner mold at the point where the inner mold was detached; the detachment from the outer mold and the detachment from the inner mold can also be regarded as happening simultaneously, so that the concrete pipe after detaching from the outer mold will not be unstable under the support of the inner mold.
[0018] 3. When detaching from the inner mold, the concrete pipe is stably supported by the clamping and transporting mechanism. As the inner mold, supported by the demolding platform, detaches from the concrete pipe downwards, the clamping and transporting mechanism moves the concrete pipe upwards and then horizontally to the right to the storage location. During this operation, the clamping and transporting mechanism moves the concrete pipe to the storage location, and the inner mold on the demolding platform moves downwards, while the inner mold is transported to the placement station via the rotating track. Simultaneously, the demolding platform rises back to the worktable, and the clamping and transporting mechanism moves to the left back to the detached inner mold location. The concrete pipe detached from the outer mold and the inner mold also move to the detached inner mold location. Performing different operations within the same timeframe shortens the working time and improves production efficiency to some extent. Attached Figure Description

Detailed Implementation
[0030] To further illustrate the technical means and effects of the present invention in achieving the intended purpose, the following detailed description of the specific implementation methods, structures, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.
[0031] like Figure 1-9 As shown, a rapid demolding device for jacking pipe production includes a demolding workbench 001. The upper surface of the demolding workbench 001 is symmetrically provided with sliding grooves 0011. The demolding workbench 001 is provided with an outer mold release point 003 and an inner mold release point 004 from left to right. The upper surface of the demolding workbench 001 receives and transports the mold and concrete pipe 3 that need to be demolded. The mold includes an outer mold 1 and an inner mold 2. The concrete pipe 3 is sleeved on the outside of the inner mold 2. The outer mold 1 is sleeved on the outside of the concrete pipe 3. The bottom edge of the inner mold 2 protrudes outward and can be embedded in the outer mold 1. The top of the inner mold 2 is provided with a connecting groove 20 and the connecting groove 20 is provided with threads.
[0032] A frame 01 is provided above the demolding worktable 001. A connecting support column 101 is provided inside the frame 01. The top of the inner mold 2 is connected to the frame 01 through the connecting support column 101. The top of the connecting support column 101 is provided with a toothed structure and the bottom is provided with threads. The bottom of the connecting support column 101 is threadedly connected to the inner mold 2. A transmission belt is provided on opposite sides inside the frame 01. The transmission belt is driven by a motor 011 provided at the bottom of the frame 01. The surface of the transmission belt is provided with toothed protrusions that are adapted to the surface of the connecting support column 101. The transmission belt drives the connecting support column 101 to rotate and move left and right. The connecting support column 101 then drives the inner mold 2 to move.
[0033] Below the outer mold detachment point 003, there is an outer mold rotation track support 03. Two sets of demolding lifting cylinders 032 are symmetrically arranged on the upper surface of the outer mold rotation track support 03. An outer mold rotation worktable 002 is provided on the left front side of the demolding worktable 001. An opening adapted to the outer mold 1 is opened on the right side of the outer mold rotation worktable 002. The two sets of demolding lifting cylinders 032 are located below the outer mold detachment point 003 and below the opening, respectively. An adsorption plate is provided at the top of the demolding lifting cylinder 032, and the outer mold 1 is adsorbed and fixed by the adsorption plate to facilitate the separation of the outer mold 1.
[0034] The outer mold rotary track support 03 is symmetrically provided with outer mold rotary tracks 031 on the upper inner side. The two outer mold rotary tracks 031 are provided with limit protrusions 0311 on the opposite side surface, and the two outer mold rotary tracks 031 are connected and rotated through the connecting shafts 0312 set at the front and rear ends.
[0035] A lifting support seat 022 is fixedly installed at the bottom middle position of the outer mold rotary track support seat 03. An oiling support table 02 is installed on the upper telescopic part of the lifting support seat 022. An annular protruding oiling part 021 is provided on the outer surface of the oiling support table 02.
[0036] When the outer mold 1 moves downward, the oiling support platform 02 can support the bottom of the inner mold 2 and the concrete pipe 3, while preventing the inner mold 2 and the concrete pipe 3 from being affected when the outer mold 1 is demolded downward. The oiling support platform 02 only begins to move downward when the top of the outer mold 1 is lower than the upper surface of the demolding worktable 001. Under the action of the lifting support seat 022 and the demolding lifting cylinder 032, the oiling support platform 02 can move the outer mold 1 downward to the outer mold rotation track 031 while applying oil to the inner wall of the outer mold 1. Then, the demolded and oiled outer mold 1 is conveyed forward through the outer mold rotation track 031 and then conveyed to the material placement station through the outer mold rotation worktable 002.
[0037] The inner mold release point 004 is provided with a demolding support platform 402 parallel to the upper surface of the demolding workbench 001. The inner mold rotation track 04 is provided below the inner mold release point 004. The right side of the demolding workbench 001, corresponding to the inner mold release point 004, is provided with a clamping and transporting mechanism 05, which is used to assist in separating the concrete pipe 3 from the inner mold 2 and to transport the separated concrete pipe 3 to the storage area.
[0038] While the clamping and transporting mechanism 05 clamps the concrete pipe 3 and moves it upward, the demolding support platform 402 drives the inner mold 2 to move downward until the inner mold 2 moves to the inner mold rotation track 04. The clamping and transporting mechanism 05 clamps the concrete pipe 3 and moves it to the right to the storage location, thereby realizing the separation of the concrete pipe 3 and the inner mold 2.
[0039] The inner mold rotary track 04 includes a support platform 044. Support plates 041 are symmetrically installed on both sides of the top of the support platform 044. Conveyor belts 042 are provided on the two side support plates 041. Multiple limiting baffles 043 are provided at corresponding positions on opposite sides of the two conveyor belts 042. The multiple limiting baffles 043 are evenly spaced. The two ends of the conveyor belts 042 are connected to the support plates 041 through support blocks 0421. The support platform 044 is provided with clearance holes to accommodate the demolding support platform 402, so that the inner mold 2 moves downward under the drive of the demolding support platform 402 and is transferred between the inner mold 2 and the limiting baffles 043 on the inner mold rotary track 04. A lifting support seat 401 is fixedly connected to the bottom of the demolding support platform 402. The lifting support seat 401 is used to support the demolding support platform 402 to connect and perform lifting movements.
[0040] The second lifting support base 401 lifts the demolding support platform 402. The bottom end of the second lifting support base 401 is equipped with a drive motor to drive the second lifting support base 401 to rotate, thereby driving the rotation and lifting of the demolding support platform 402 to separate it from the concrete pipe 3, and to separate the inner mold 2 from the connecting support column 101.
[0041] The clamping and transporting mechanism 05 is provided with translation slide rails 051 on both sides, and a support seat 052 that can move on the translation slide rail 051 is provided on the translation slide rail 051; a telescopic cylinder 053 is provided inside the support seat 052, and the telescopic cylinder 053 is connected to the clamping plate 054.
[0042] The slide groove 0011 on the surface of the demolding worktable 001 is connected to the limiting slide groove 4021 and the limiting groove 4022 provided on the demolding support table 402; the protrusion 201 provided at the bottom of the inner mold 2 cooperates with it.
[0043] In use, the present invention firstly, the mold to be demolded and the concrete pipe 3, under the action of the connecting support column 101 connected to the inner mold 2, and driven by the frame 01 and with the cooperation of the bottom protrusion 201 of the inner mold 2, move to the point of separation from the outer mold 003; the demolding lifting cylinder 032 moves the outer mold 1 downward. During the downward movement, the oiling part of the oiling support platform 02 located below the demolding worktable 001 contacts the inner wall of the outer mold 1 for oiling; when the outer mold 1 moves downward to the top below the upper surface of the demolding worktable 001, the oiling support platform 02 begins to perform oiling movement from top to bottom on the interior of the outer mold, and applies oil to the inner wall of the outer mold 1 until the outer mold 1 moves downward to the outer mold rotation track 031, and the oiling support platform 02 descends to the bottom;
[0044] When the outer mold 1 moves downwards until its top is below the upper surface of the demolding worktable 001, while the outer mold 1 is being demolded, the inner mold 2 supports the concrete pipe 3 and continues to move to the right until it is detached from the inner mold 004. Under the limiting position of the concrete pipe 3 held by the clamping and transporting mechanism 05, the demolding support platform 402, driven by the rotation of the bottom lifting support seat 401, separates the top of the inner mold 2 from the upper connecting support column 101, and gradually connects and fixes the protrusion 201 at the bottom of the inner mold 2 with the limiting groove 4022 on the demolding support platform 402. Then it moves downwards until the inner mold 2 moves to the inner mold rotation track 04. The clamping and transporting mechanism 05 clamps the concrete pipe 3 and moves it to the right to the storage position, thereby realizing the separation of the concrete pipe 3 and the inner mold 2. When the inner mold 2 falls to the bottom support platform 044, the inner mold rotation track 04 needs to be driven by the demolding support platform 402 in the opposite direction of the bottom lifting support seat 401 to move the inner mold 2 back to the material placement position.
[0045] When the inner mold 2 is disengaged from the work, the outer mold 1 is simultaneously transported by the outer mold rotary track 031 to the outer mold rotary worktable 002 after demolding and oiling, and then transported back to the cloth-making station.
[0046] Similarly, the new mold to be demolded and the concrete pipe 3 move to the right in sequence to detach from the outer mold 1, apply oil, and separate the inner mold 2 and the concrete pipe 3, and then transport the concrete pipe 3 to the storage location.
[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
