[0002] A large number of water supply, drainage, sewage diversion and other engineering construction and municipal pipeline construction inevitably need to cross roads, mountains or existing structures. Commonly used methods in projects include jacking construction, dragging pipes, shallow buried excavation, open excavation and closure. When the municipal pipeline construction crosses mountains, rivers or sensitive buildings (structures), in order to ensure the safe and effective operation of the planned pipeline and the safety of existing structures, the project generally sets up a protective casing or lining structure, and at the same time needs to transport and install the inner casing in a small space.

[0003] In order to further save construction costs, the distance between the inner and outer casings is constantly reduced. The inner casing operation is in a limited space environment. The space on both sides of the pipeline is narrow and there is not enough working space, which limits the pipeline installation operation space and transportation in the tunnel. In addition, the tunnel section is long and the long-distance transportation efficiency of the pipeline is low. Therefore, seeking a small space inner casing pipeline transportation and installation trolley has become a common issue in the industry.

[0004] Disadvantages of the prior art.

[0005] Based on this, the utility model designs a casing installation trolley to solve the above problems. Utility Model Content

[0029] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. However, the present invention can be implemented in a variety of different ways as defined and covered below.

[0030] See also Figure 1-7 The utility model provides a casing installation trolley, which is used for transporting and installing casings in narrow spaces such as protective sleeves or linings.

[0031] Specifically, the casing installation trolley includes a vehicle head and a vehicle body, the vehicle body is used to place the casing and adjust the position of the casing when the casings are docked, and the vehicle head is used to drive the vehicle body to move in a narrow space.

[0032] like Figure 1-2 As shown, the vehicle body includes a bracket 1 with running wheels 15 at the bottom and a first adjustment component and a second adjustment component located on the bracket 1. The first adjustment component and the second adjustment component are used to realize multi-directional adjustment of the sleeve on the bracket 1, making it more convenient to dock the sleeve in a small space.

[0033] Figure 3 An example of a bracket 1 is shown. In this example, the cross-section of the bracket 1 is an arc shape, and the diameter of the arc is designed according to the diameter of the casing to be transported, so that when the casing is placed on the upper arc surface of the bracket 1, the center of the circular cross-section of the casing coincides with the center of the circular cross-section of the bracket 1, and the casing can be completely fitted on the upper arc surface of the bracket 1, and the casing can be preliminarily aligned. At the same time, the stability of the casing during transportation can be ensured without fixing the casing by a fixing device, eliminating the traditional process of fixing the casing and disassembling the fixing device, making the transportation of the casing more convenient. When the installation position of the casing is a protective cover or a circular lining, the bracket 1 with an arc-shaped cross-section can be closer to the bottom surface of the protective cover or lining, causing the space for placing the casing to sink as a whole. After the casing is placed on the bracket 1, the distance between the casing and the protective cover or lining is smaller, reserving more space for subsequent adjustment of the casing.

[0034] Figure 1 An example of a first adjustment component is shown, the first adjustment component includes a cross beam 2 and a first vertical beam 3 and a second vertical beam 4 fixed at both ends of the cross beam 2, the cross beam 2, the first vertical beam 3 and the second vertical beam 4 are all hydraulic telescopic rods, the bottom end of the first vertical beam 3 is fixed to the side of the bracket 1 close to the front of the vehicle, and the top end is fixedly connected to the cross beam 2, the second vertical beam 4 is fixed to the end of the cross beam 2 away from the first vertical beam 3, and the bottom end of the second vertical beam 4 is a free end, as shown in FIG. Figure 4 As shown, when the sleeve is placed on the bracket 1 for transportation, the cross beam 2 is installed with one end of the second vertical beam 4 and the second vertical beam 4 is located in the sleeve. When the sleeve is transported to a certain position and needs to be docked, as shown in FIG. Figure 7 As shown, the cross beam 2 is unfolded to send the second vertical beam 4 out of the sleeve on the bracket 1 and into the installed sleeve. Next, the second vertical beam 4 is unfolded so that its bottom end abuts against the inner cavity of the installed sleeve. Figure 7As shown, at this time, the bottom ends of the first vertical beam 3 and the second vertical beam 4 are fixed, and then the cross beam 2 is raised by simultaneously unfolding the first vertical beam 3 and the second vertical beam 4, and the sleeve is lifted by the cross beam 2 in contact with the top of the inner cavity of the sleeve, and the sleeve is lifted to the docking height and then stops, and then the front of the vehicle drives the vehicle body to continue to approach the installed sleeve, and at the same time the cross beam 2 begins to retract at the same speed, while keeping the position of the second vertical beam 4 unchanged, the sleeve on the bracket 1 is slowly moved to the installed sleeve, and finally the two sleeves are docked, and the second vertical beam 4 is moved into the installed sleeve by the retractable cross beam 2, and the sleeve to be installed is lifted by the cross beam 2 with the inner cavity of the installed sleeve as the support surface, without occupying the external space of the sleeve, with lower space requirements, more convenient to use in a small space, and at the same time the overall device has a simple structure, easy to use, and lower manufacturing cost and later operation and maintenance cost.

[0035] Furthermore, the axial directions of the first vertical beam 3 and the second vertical beam 4 are the same, so that the adjustment directions of the first vertical beam 3 and the second vertical beam 4 on the cross beam 2 are the same.

[0036] like Figure 5 As shown, in some examples, the crossbeam 2 is composed of three telescopic joints, and contact blocks 5 are fixedly installed on the top of the two telescopic joints with smaller diameters. The height of the contact blocks 5 is designed according to the diameter of the telescopic joints, so that the tops of all the contact blocks 5 are at the same horizontal height as the top of the telescopic joint with the largest diameter. In this way, when the sleeve is lifted from the inner cavity of the sleeve by the crossbeam 2, the sleeve can be prevented from tilting due to the diameter difference of the telescopic joints, which facilitates rapid docking between the sleeves.

[0037] Figure 3 An example of a second adjustment component is shown. In this example, the second adjustment component includes a plurality of jacks 6, which are symmetrically arranged on the bracket 1 with the axis of the bracket 1 as the center. After the crossbeam 2 lifts the sleeve, the sleeve is pushed from the side by the jack 6 to adjust the left and right position of the sleeve. In conjunction with the first adjustment component, the height, front and rear position, and left and right position of the sleeve can be adjusted. When docking the sleeves, the first adjustment component and the second adjustment component can be used respectively according to the actual deviation of the sleeves to ensure that the sleeves can be docked smoothly.

[0038] like Figure 2 As shown, in some examples, a groove is provided on the upper arc surface of the bracket 1, and the jack 6 is installed in the groove. The depth of the groove is not less than the length of the jack 6 in the initial state, so that the jack 6 will not protrude from the upper arc surface of the bracket 1 in the initial state, and will not affect the normal prevention sleeve on the bracket 1.

[0039] Specifically, Figure 4As shown, the bracket 1 includes a main bracket 11, a wing plate 12, a transverse stiffening rib 13 and a longitudinal stiffening rib 14. The transverse stiffening rib 13 and the longitudinal stiffening rib 14 are respectively fixed on the upper end surface and the lower end surface of the main bracket 11, and the wing plate 12 is fixed on both sides of the main bracket 11 to improve the bearing strength of the bracket 1 and increase stability.

[0040] like Figure 3 As shown, in some examples, a mounting groove for mounting a travel wheel 15 is provided at the bottom of the bracket 1. The travel wheel 15 is accommodated in the mounting groove, thereby further reducing the space between the bracket 1 and the bottom of the protective cover or lining, thereby increasing the adjustable range of the sleeve on the bracket 1.

[0041] Figure 1 An example of a vehicle head is shown. In this example, the vehicle head includes an operating room 7 and a power room 8. Power wheels are installed on both sides of the power room 8 so that the vehicle head can drive the bracket 1 to move. A hydraulic cylinder is provided in the power room 8 for providing liquid with pressure energy to the jack 6, the first vertical beam 3, the second vertical beam 4 and the cross beam 2. When in use, the power wheels and electrical equipment such as the hydraulic cylinder can be controlled by the control device in the operating room 7.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
