Description

  The present invention relates to an elevating device that has a function of moving an object stocked at a low position to a high position and further moving the object to another, and can contribute to efficient transportation of the object.

  In view of the impact on traffic, there are few cases where traffic of vehicles other than the construction lane is restricted in the construction of repairing existing pavements. Therefore, there are many cases where the working range for pavement work is extremely narrow. When the working space is small, it is often the case that the paving material is transported by hand-held unicycle, for example, relying on human power to transport the paving material.

  Also, in construction sites where a small work space and a large space where heavy machinery can be introduced are mixed, the paving material is used as heavy machinery when the narrow space is transported manually and then reaches a wide space. It is efficient and safe to transfer and transport the paving material with this heavy machine.

  In order to transfer the pavement material from the hand-held unicycle to the heavy machinery, some means such as a device enabling this is necessary. This is because it is difficult to manually transfer the pavement material because the storage portion of the hand-held unicycle is lower than the storage portion of the heavy machinery. For example, it is assumed that a wheel loader as proposed in Patent Document 1 below is used as a means for moving a pavement material stocked at a low position to a high position and moving the pavement material to another position.

  However, there may be construction sites where there is not enough space for the wheel loader to change direction. Also, the height of the wheel loader housing may not be low enough to receive the pavement material from the hand unicycle housing. It is conceivable to use a belt conveyor to move the pavement material from the low position to the high position, but the time to load the pavement material from the belt conveyor to the heavy machinery (heavy machine restraint time) becomes longer, so it is more efficient than relying on human power May be worse.

JP 2013-167098 A

  As described above, in work to repair existing pavement, after transporting a narrow place manually, the pavement material is transferred to heavy equipment when it reaches a wide place, and it is efficient to transport the pavement material with this heavy equipment Some means such as a typical device is needed. In particular, there is a demand for a function of stocking pavement material at a low position, moving it to a high position, and moving it to another position.

  The present invention has been proposed in view of the above circumstances, and has a function of moving an object stocked at a low position to a high position and further moving the object to another, and can contribute to efficient transportation of the object. An object is to provide a lifting device.

  In order to achieve the above object, the present invention provides an elevating device for moving an object from a low position to a high position, comprising: a receiving unit that receives the object; and an in-device moving mechanism that moves the receiving unit within the device. And an in-apparatus moving mechanism that lifts and lowers the receiving section from the low position to the high position or from the high position to the low position, and lifts one end of the receiving section to receive the receiving section. An elevating device characterized by having an inclining means for inclining.

  The receiving section is tilted by the tilting means after being raised from the low position to the high position by the elevating means.

  The receiving portion is raised from the low position to the high position by the elevating means in a substantially horizontal state.

  The receiving portion is located below one side of the lifting device when in the low position, and is located above the other side of the lifting device when tilted. One side of the lifting device refers to the side where the pavement material is carried to the lifting device. That is, the side that receives the pavement material at the receiving portion is called one side of the lifting device. In addition, the other side of the lifting device refers to the side where the pavement material is transferred from the lifting device to another, for example, the side where the pavement material is transferred to the accommodating portion of the heavy equipment for transportation waiting at a high position.

  When the receiving portion is tilted by the tilting means, the other end portion serves as a fulcrum.

  The elevating means is a parallel link.

  The tilting means is a hydraulic cylinder or an air cylinder.

  The present invention relates to a lifting device that moves an object from a low position to a high position, and includes a receiving unit that receives the object, and an in-device moving mechanism that moves the receiving unit within the device. In addition, the in-apparatus moving mechanism has a lifting unit that raises and lowers the receiving unit from the low position to the high position, or from the high position to the low position, and an inclination unit that lifts one end of the receiving unit and tilts the receiving unit. is there. Therefore, by the elevating means and the tilting means of the moving mechanism in the apparatus, for example, in the reinforced concrete pavement work of the existing bridge, the pavement material is stocked in the receiving part at the low position, and this is moved to the high position. The pavement material can be made to flow along this slope and be transferred to another. That is, it can be provided as an elevating device that is efficient for transferring paving material to a heavy machine when a narrow place is transported manually and then reaches a wide place.

  The present invention has a configuration in which the receiving portion is tilted by the tilting means after being raised from the low position to the high position by the lifting means. Thereby, it is possible to reliably realize the function of stocking the pavement material at a low position, moving it to a high position, and moving it to another position.

  The present invention is configured to be raised from a low position to a high position by an elevating means while the receiving portion is in a substantially horizontal state. Thereby, since the receiving part is raised by the elevating means while being maintained in a substantially horizontal state, the pavement material accommodated in the receiving part can be moved from the low position to the high position without spilling.

  The present invention is configured to be positioned below one side of the lifting device when the receiving portion is at a low position and positioned above the other side of the lifting device when tilted. Thereby, the pavement material which existed in the one side lower part (low position) of the raising / lowering apparatus which is this invention can be moved to the other side upper part (high position). In other words, the pavement material can be stocked at a low position without moving against the conveying direction of the pavement material, moved to a high position, and further transferred to another position.

  In the present invention, when the receiving portion is tilted by the tilting means, the other end portion is a fulcrum. As a result, after the pavement material is moved to a high position, the other end becomes a fulcrum when the one end of the receiving portion is lifted and the receiving portion is tilted. Without spilling, it can be moved to another place (for example, a storage unit of a heavy machine waiting at a high position). Since the other end of the receiving part will be located on the other side of the lifting device, do not oppose the conveyance direction of the pavement material, stock the pavement material smoothly at a low position, move this to a high position, Furthermore, it can assume the function of moving to another.

  According to the present invention, the receiving unit can be moved up and down from the low position to the high position or from the high position to the low position with a relatively simple structure by the configuration in which the lifting means is a parallel link. In addition, with the configuration in which the tilting means is a hydraulic cylinder or an air cylinder, the receiving portion can be tilted by lifting one end of the receiving portion with a simple structure. Therefore, the pavement material can be stocked at a low position, moved to a high position, and further transferred to another with a simple structure.

  Hereinafter, the configuration of the lifting device according to the present invention and an embodiment in which the pavement material is transferred to a transporting heavy machine using the same will be described in detail with reference to the drawings. The embodiment described below is merely an example of the present invention. The present invention can be modified in various ways without departing from the scope of the claims.

  For example, as shown in FIG. 1, the present invention includes a receiving unit 1 that receives an object and an in-device moving mechanism 2 that moves the receiving unit 1 within the device, and moves the object from a low position to a high position. The present invention relates to a hopper device A as a lifting device that can be moved. In the present invention, the hopper apparatus A is provided as an apparatus capable of improving the efficiency of, for example, transferring a paving material to a transporting heavy machine when a narrow place is manually transported and then reaches a wide place. This aims to improve the efficiency of time and economy, such as shortening the construction period of pavement construction and reducing labor costs.

  As shown in FIGS. 1 to 3, the hopper device A includes a hopper-like receiving portion 1 in which a pyramid portion 11, which is a concave portion for storing a paving material, and an inside of the device for moving the receiving portion 1 in the device. And a moving mechanism 2. The in-apparatus moving mechanism 2 includes elevating means for raising and lowering the receiving section 1 from the low position to the high position, or from the high position to the low position, and tilting means for lifting the one end 1a of the receiving section 1 and tilting the receiving section 1. Have.

  In the present embodiment, the parallel link 21 is employed as the lifting means for lifting the receiving unit 1 from the low position to the high position or from the high position to the low position. A hydraulic cylinder 22 is employed as the tilting means for lifting the one end 1 a of the receiving portion 1 and tilting the receiving portion 1. Note that the one side of the hopper device A refers to the side on which the paving material is conveyed to the hopper device A. That is, the side that receives the paving material in the receiving unit 1 is referred to as one side of the hopper device A. Further, the other side of the hopper device A refers to a side where the pavement material is transferred from the hopper device A to another, for example, the side where the pavement material is transferred to a storage unit of a transport heavy machine waiting at a high position.

  By adopting the parallel link 21 as the lifting means, the hopper device A can lift the pyramid portion 11 of the receiving portion 1 from the low position to the high position in a substantially horizontal state. Further, it is possible to easily achieve movement within the apparatus such that the receiving unit 1 is positioned below one side of the hopper apparatus A when in the low position and positioned above the other side of the hopper apparatus A when tilted. Can do. In the present invention, any lifting / lowering means that enables the state of the receiving unit 1 and movement within the apparatus can be adopted without being limited to the parallel link 21.

  The hopper device A can easily tilt the one end 1a of the receiving portion 1 after being raised to a high position by adopting the hydraulic cylinder 22 as the tilting means. Further, when the receiving portion 1 is tilted by the hydraulic cylinder 22, a configuration in which the one end portion 1a is lifted and the other end portion 1b is used as a fulcrum, for example, a shaft body 12a is provided on the other end portion 1b and is pivotally supported. This can be achieved with an easy structure. In the present invention, any lifting means that enables the receiving portion 1 to be inclined can be adopted without being limited to the hydraulic cylinder 22. For example, an air cylinder or other telescopic actuator can be employed.

  The hopper device A can move (reverse) the pavement material conveying direction to move the pavement material that was in one side lower (low position) to the other side upper (high position) and further to the other side. Absent. When the receiving portion 1 is located at a high position, the other end 1b is a fulcrum above the other side of the hopper device A, and the one end 1a is lifted and inclined by the hydraulic cylinder 22, so that the pavement in the receiving portion 1 is paved. By flowing the material along the slope, it is transferred to the other. In the hopper device A, the receiving unit 1 can be lowered from the other side upper side (high position) to the one side lower side (low position) by the hydraulic cylinder 22 and the parallel link 21.

  Hereinafter, the structure of the hopper device A will be described in detail with reference to FIGS.

  As shown in FIG. 1, the receiving portion 1 is particularly composed of a pyramid portion 11 that is a concave portion for accommodating a pavement material, and a frame body 12 that surrounds the pyramid portion 11. The bottom portion 11a forming the concave portion of the pyramid portion 11 is inclined so that the concave portion on the one end portion 1a side of the receiving portion 1 is large and the concave portion is reduced toward the other end portion 1b side. Such a concave shape of the pyramid portion 11 is a shape suitable for accommodating more paving material in the pyramid portion 11 while keeping in mind that the other end 1b side of the receiving portion 1 is inclined and moved to the other. Become.

  In the receiving portion 1, one end 22 a of a hydraulic cylinder 22 is connected to the middle of the bottom portion 11 a of the inclined pyramid portion 11 (substantially central portion). Further, the frame body 12 of the other end portion 1b of the receiving portion 1 is provided with a shaft body 12a serving as a fulcrum when the receiving portion 1 is tilted, and the other end 22b of the hydraulic cylinder 22 is connected. The other end portion of the pyramid portion 11 is disposed in contact with the shaft body 12a serving as the fulcrum.

The capacity of the pavement material that can be received by the pyramid portion 11 is preferably, for example, 0.1 to 0.3 m ³ from the viewpoint of efficient construction. In this embodiment, the capacity | capacitance is 0.2 m < ³ > (for 1 batch of the manufacturing apparatus of a pavement material), for example. Preferably correspond to the ability of an apparatus for producing a paving material from the viewpoint of efficiency (at full capacity), it is suitably a 0.1～0.3M ³ in the present embodiment.

  The parallel links 21 are composed of two pairs of a total of four rod bodies, which are respectively on the frame body 12 on one side and the other side of the main body A1 in the hopper device A and on the one end 1a and the other end 1b side in the receiving portion 1. And connected to. The parallel link 21 moves up and down from the low position to the high position, or from the high position to the low position in a substantially horizontal state, particularly when the two to four parallel movements always operate in parallel. It becomes. Moreover, the pavement material which was on the one side lower side (low position) can be moved to the other side upper side (high position) without going against (reversing) the conveyance direction of the pavement material. As a power source for operating the parallel link 21, various drive devices such as an electric cylinder, an engine, a hydraulic pressure, or an electric motor can be adopted. In this embodiment, a hydraulic cylinder is employed.

  As described above, one end 22a of the hydraulic cylinder 22 is connected to the middle of the inclination of the bottom part 11a of the pyramid part 11 (substantially central part). The other end 22 b of the hydraulic cylinder 22 is connected to the frame body 12 of the other end 1 b of the receiving portion 1. Since the frame body 12 is pivotally supported by the shaft body 12a at the other end portion 1b, the receiving portion 1 can be lifted by the one end 22a with the other end 22b as a fulcrum by the expansion and contraction of the hydraulic cylinder 22.

  Thereby, the one end part 1a side of the receiving part 1 is lifted, and the pyramid part 11 inclines. Since the other end portion of the pyramid portion 11 is disposed in contact with the shaft body 12a, it is substantially immovable. Further, when the hydraulic cylinder 22 expands and contracts and the one end side of the pyramid portion 11 is lifted and tilted, the parallel link 21 does not move. This is because the 2 to 4 rod bodies of the parallel link 21 are all connected to the frame body 12.

  As a power source for operating the hydraulic cylinder 22, various drive devices such as an electric cylinder, an engine, a hydraulic pressure or an electric motor can be adopted. Further, for convenience of movement, the hopper device A can be provided with wheels T in its main body A1 and with an engine or the like so that it can run on its own. In view of operations such as hand pressing of the hopper device A, it is preferable to provide the handrail H. In the present embodiment, E is a hydraulic power package. The hydraulic power package is a device for operating the hydraulic cylinder 22 by generating a hydraulic pressure source by rotating a hydraulic pump with an electric motor.

  Hereinafter, the operation of the hopper device A will be described in detail with reference to FIG.

  First, the pavement material is directly fed into the pyramid portion 11 of the receiving unit 1 in the hopper device A from the manufacturing apparatus for manufacturing the pavement material. Further, the pavement material supplied from the manufacturing apparatus to the hand-held unicycle is thrown into the pyramid portion 11 of the receiving unit 1 through the hand-held unicycle. Or these are performed together. When these are used in combination, a plurality of, for example, two hopper devices A are preferably introduced. At this time, as shown in FIG. 4A, in the hopper device A, the receiving portion 1 is located on one side lower side (low position). Therefore, it is possible to input the pavement material easily into the pyramid portion 11 of the receiving portion 1 located at a low position through a hand-held unicycle as well as directly from the manufacturing apparatus.

  Next, the pavement material received by the pyramid portion 11 of the receiving portion 1 lifts the pyramid portion 11 to a high position with the parallel link 21 in a substantially horizontal state. Accordingly, as shown in FIG. 4B, the pavement material is not spilled from the pyramid portion 11 to the outside and the pavement material is not conveyed against the conveying direction of the pavement material from one side lower side (low position). It can be transferred to the upper side (high position) on the other side.

  Further, as shown in FIG. 4 (c), on the other side upper side (high position) of the hopper device A, one end side 1a of the receiving part 1 in the pyramid part 11 is lifted by the hydraulic cylinder 22, and the receiving part 1 (pyramidal part) 11) is tilted. At this time, the other end portion of the pyramid portion 11 is substantially immovable because the shaft body 12a of the frame body 12 serving as a fulcrum for tilting the receiving portion 1 is disposed in contact with the fulcrum. That is, since the other end portion of the pyramid portion 11 is fixed and the pyramid portion 11 is inclined, the pavement material accommodated in the pyramid portion 11 can be moved to another place without spilling. For example, as shown in FIG. 5, it can move to the bucket B as an accommodating part of the heavy machine for conveyance waiting in a high position.

  Here, an example in which two pavement material manufacturing apparatuses are arranged in the longitudinal direction and the pavement material is transported to a construction machine that is 130 m away will be taken, and an explanation will be given as to how far the reduction of personnel can be promoted. In this case, according to the conventional method in which the pavement material is transported over the whole process with a hand-held unicycle, 33 hand-held unicycles and personnel are required.

  On the other hand, when introducing the hopper device A and the heavy equipment for transportation according to the present invention, the number of hand-held unicycles required was six. In other words, six people should be secured. Therefore, even if one person who operates heavy equipment for transportation and one person who operates the hopper device A are added, 25 persons can be reduced as compared with the prior art. The transport time is further reduced by storing the pavement material from the hand-held unicycle to the hopper device A using the time it takes for the transport heavy equipment to transport the pavement material to the construction site and return to the position of the hopper device. Will be.

  Therefore, according to the present invention, the minimum necessary manpower is achieved while mechanization is performed using the hopper device A that can perform the function of stocking the pavement material at a low position, moving the pavement material to a high position, and moving it to another position. By this, transportation of the paving material to the paving position can be realized. Therefore, it can contribute to construction such as reinforced concrete pavement work of the existing bridge which is efficient in terms of time and cost. That is, the hopper device A can be provided as an efficient lifting device for transferring the paving material to a heavy machine when the hopper device A reaches a wide place after being transported manually in a narrow place.

  Further, the receiving unit 1 is lifted from the low position to the high position by the parallel link 21 and then tilted by the hydraulic cylinder 22. From the low position to the high position by the parallel link 21 while the receiving unit 1 is in a substantially horizontal state. With the configuration that can be raised, pavement material is stocked at a low position, and the function of moving it to a high position and moving to another is ensured. A configuration in which the receiving unit 1 is positioned below one side of the hopper device A when the receiving unit 1 is in a low position and is positioned above the other side of the hopper device A when tilted, and when the receiving unit 1 is tilted by the hydraulic cylinder 22 Further, due to the configuration in which the other end is a fulcrum, a series of transportation of the paving material can be smoothly advanced. In the present invention, these actions are realized by simple structures such as the parallel link 21 and the hydraulic cylinder 22.

  As mentioned above, although embodiment regarding this invention was described, this invention is not limited to the said embodiment. The present invention can be modified in various ways without departing from the scope of the claims. For example, the present invention can be used when the reinforced concrete pavement for an existing bridge is implemented. However, the present invention is not limited to this, and can be applied to various paving works. Of course, the pavement material to be transported is not limited to the FRC or SFRC used in the reinforced concrete pavement construction of the existing bridge, and other materials can be applied.

  In addition, the present invention is not limited to road pavement work, etc., but in applications that require the function of moving an object stocked at a low position to a high position and moving the object to another, the efficiency of the object Can contribute to efficient transportation.
