Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of drainage structure construction equipment in civil engineering, and particularly to a device for lifting, installing and removing precast gutter covers. Background Art
[0002] In the field of drainage structure construction in civil engineering, drainage ditches are the most common structural form. After mechanically excavating the ditch and pouring concrete, various forms of precast gutter covers are installed thereon. The currently used precast gutter covers are generally made of reinforced concrete precast or alloy materials, and their specifications and dimensions are generally large, ranging from 60 cm to 4 m in length per section, to meet the laying requirements of long lines.
[0003] For the installation and removal of precast gutter covers, the current construction methods are as follows:
[0004] ① Manually carry it to the corresponding position for installation, and this process requires one or more people to cooperate to complete the installation.
[0005] ② Manually use a steel wire rope to hang the precast gutter cover on the bucket of an excavator, and mechanically lift it to the corresponding position, and manually cooperate with the machine to place it in place and remove the steel wire rope. This process requires multiple people to cooperate for installation.
[0006] Existing problems:
[0007] ① When using pure manual installation, workers need to bend down back and forth, pick up, then go up and down slopes and bend down for installation, which consumes a great deal of physical strength of workers and is prone to occupational diseases such as lumbar muscle strain.
[0008] ② When multiple people cooperate for installation, it is relatively difficult to coordinate among individuals, and it is easy to cause chaos and danger.
[0009] ③ Whether it is one person or multiple people, the precast gutter cover needs to be lifted to a certain height to keep the body upright to facilitate walking during installation. However, at this height, once it falls, it will cause serious object hitting injuries to workers.
[0010] ④ When using mechanical installation, the mechanical usage cost is relatively high, and manual assistance is still required, increasing the cost.
[0011] ⑤ When finally positioning and installing, it is necessary to finely adjust the position of the precast gutter cover, and the fingers of workers are easily stuck in the installation gap between the precast gutter cover and the edge of the gutter, causing injuries.
[0012] ⑥ After installation, when adjustment or replacement is required in the later stage, the cost of calling machinery for a small amount of construction is too high, but manual operation is also relatively difficult and the efficiency is low. Content of the Utility Model
[0013] The present utility model is made to solve the above technical problems, and one of its purposes is to provide a lifting, installing and disassembling device for precast gutter covers, which is convenient for workers to construct precast gutter covers quickly.

[0048] Unless otherwise clearly specified and defined, the terms "installation", "connection", and "linkage" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0049] According to an embodiment of the present utility model, a device for lifting, installing, and disassembling a precast gutter cover plate is provided. Please refer to Figures 1 to 5 , the device for lifting, installing, and disassembling a precast gutter cover plate includes: a main rod 1, a first clamping plate 2, a second clamping plate 3, and two traction cables 4. The main rod 1 is a rod-shaped body, which is vertically arranged during use. One end of the first clamping plate 2 and the second clamping plate 3 is rotatably connected to the lower end of the main rod 1. Specifically, a connecting head is formed at the lower end of the main rod 1, a transverse shaft hole is provided in the middle of the connecting head, a rotating shaft is installed in the shaft hole, and one end of the first clamping plate 2 and the second clamping plate 3 close to the main rod 1 is rotatably arranged on the rotating shaft, and the first clamping plate 2 and the second clamping plate 3 are respectively arranged on both sides of the main rod 1. When the ends of the first clamping plate 2 and the second clamping plate 3 away from the main rod 1 rotate downward, they open to both sides to form Figure 1 the state shown in; when the ends of the first clamping plate 2 and the second clamping plate 3 away from the main rod 1 rotate upward, they fold towards the middle until the sides are close to the side wall of the main rod 1 to form Figure 2 the state shown in.
[0050] The two traction cables 4 are slidably arranged on the main rod 1 along the long direction. The upper ends are fixedly connected with a first handle 5, and the lower ends are respectively connected to the ends of the first clamping plate 2 and the second clamping plate 3 away from the main rod 1. Therefore, when the user lifts the first handle 5, the two clamping plates in the Figure 1 open state shown in can be rotated to the Figure 2 folded state shown in.
[0051] When it is necessary to install and disassemble the precast gutter cover plate, insert the lower end of the device in the Figure 2 state along the gap on the precast gutter cover plate and then move the first handle 5 downward to open the first clamping plate 2 and the second clamping plate 3. Then, lift the whole device to make the first clamping plate 2 and the second clamping plate 3 support on the lower surface of the precast gutter cover plate. After that, move the device to transfer the precast gutter cover plate to the position to be installed or other positions to complete the construction of the precast gutter cover plate. During the transfer, control the position of the first handle 5 so that it does not move downward to stably place the precast gutter cover plate on the first clamping plate 2 and the second clamping plate 3.
[0052] As an embodiment, when the first clamping plate 2 and the second clamping plate 3 rotate downward from the side close to the main rod 1, the rotation angle does not exceed 120°, that is, fromFigure 2 In the state shown, when the first clamping plate 2 and the second clamping plate 3 rotate downward, the rotation angle does not exceed 120°. Correspondingly, when transferring the precast gutter cover plate, the device will not fall off from the gap in the precast gutter cover plate.
[0053] For the way of limiting the rotation angle of the first clamping plate 2 and the second clamping plate 3, in one embodiment, a limiting part can be arranged at the lower end of the main rod 1. When the first clamping plate 2 and the second clamping plate 3 rotate to the maximum angle, their lower sides abut against the limiting part, and the limiting of the first clamping plate 2 and the second clamping plate 3 can be completed.
[0054] As an implementation manner, a through hole 6 for the traction cable 4 to slide is arranged in the main rod 1. The main body part of the traction cable 4 is located in the through hole 6, and it is not easily interfered by the outside during use and has good stability. In addition, when the first clamping plate 2 and the second clamping plate 3 rotate to the maximum angle, the first handle 5 abuts against the upper port of the through hole 6, which can also indirectly limit the rotation of the first clamping plate 2 and the second clamping plate 3.
[0055] As an implementation manner, a plurality of limiting plates 7 are formed vertically on the side surface of the upper end part of the main rod 1. When the first handle 5 is stuck on the limiting plate 7, a preset included angle is formed between the first clamping plate 2, the second clamping plate 3 and the main rod 1. In other words, placing the first handle 5 on different limiting plates 7 can control the rotation angle of the first clamping plate 2 and the second clamping plate 3.
[0056] For example, as Figure 1 and Figure 2 shown, in this embodiment, two columns of limiting plates 7 are formed vertically on the side surface of the upper end part of the main rod 1, and there are two limiting plates 7 in each column. When the first handle 5 is placed on the two lower limiting plates 7, the included angles between the first clamping plate 2, the second clamping plate 3 and the main rod 1 are both 90°; when the first handle 5 is placed on the two upper limiting plates 7, the included angles between the first clamping plate 2, the second clamping plate 3 and the main rod 1 are both 0°. In other words, when the first clamping plate 2 and the second clamping plate 3 rotate downward, the maximum rotation angle is 90°, and the flat precast gutter cover plate can be stably supported.
[0057] In another embodiment, two columns of limiting plates 7 can also be formed vertically on the side surface of the upper end part of the main rod 1, and there are four limiting plates 7 in each column. When the first handle 5 is placed on different limiting plates 7 from top to bottom, the included angles between the first clamping plate 2 and the main rod 1 are 0°, 60°, 90°, 120° respectively, and the included angles between the second clamping plate 3 and the main rod 1 are 0°, 60°, 90°, 120° respectively, providing multiple choices for users and being applicable to the installation and removal operations of precast gutter cover plates with different shapes.
[0058] It should be noted that in this embodiment, two columns of limiting plates 7 are formed along the vertical direction on the side surface of the upper end of the main rod 1. During use, the two ends of the first handle 5 are respectively placed on the left and right limiting plates 7, so as to achieve stable positioning. In other embodiments, only one column of limiting plates 7 can also be provided. During use, the middle part of the first handle 5 is placed on the limiting plate 7, and stable positioning can also be achieved.
[0059] As an implementation manner, a second handle 8 is formed at the upper end of the main rod 1, which is more convenient for users to operate the device to perform the installation and removal operations on the precast gutter cover plate.
[0060] In summary, the present utility model provides a professional installation and removal tool for precast gutter cover plates, which can play a key role in the process of transporting, installing and removing precast gutter cover plates, improve applicability, improve construction efficiency, improve safety, reduce the requirements for manpower and construction machinery, and is not easily caused by accidental losses due to component damage.
[0061] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
