DETAILED DESCRIPTION

[0033] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0035] In the prior art, most hoisting equipment is rail-mounted gantry crane, which has the following main problems during use: rail-mounted gantry crane requires pre-fixed tracks, which is not conducive to construction; existing construction equipment cannot meet the needs of beam transport vehicles, and prefabricated component construction can only begin after the beam erection process is completed, and both cannot be constructed at the same time; during the laying of the protective wall, the gantry crane cannot adjust its posture and cannot ensure symmetrical construction on both sides; there are problems of low construction efficiency and great construction difficulty.

[0036] Therefore, the embodiment of the present application provides a new type of multifunctional lifting and paving equipment, which adopts a trackless walking component and can meet the walking conditions under various working conditions.

[0037] like Figure 1-4As shown, the paving equipment provided by the embodiment of the present application can be used for paving the road surface 6 including different road surfaces 6 and viaduct road surfaces 6, which includes a frame 1, a lifting assembly 2, a walking assembly 3 and a detection mechanism 4. The lifting assembly 2 is installed on the frame 1 for lifting objects; the walking assembly 3 is installed on the frame 1 for driving the frame 1 to move; the detection mechanism 4 is installed on the frame 1 for detecting the distance from the frame 1 to both sides of the road surface 6, and the detection mechanism 4 transmits the detected signal to the controller, and the controller controls the walking assembly 3 to rotate, thereby changing the walking direction of the walking assembly 3. Through the setting of the detection mechanism 4, the distance from the frame 1 to both sides of the road surface 6 can be detected. When the paving equipment is offset, the detection mechanism 4 will detect that the distance between the frame 1 and both sides of the road surface 6 is not equal, so the detection mechanism 4 will transmit the signal to the controller, and the controller will control the walking assembly 3 to rotate, change the walking direction of the walking assembly 3, and at this time the walking assembly 3 will take the frame 1 to the center of the road surface 6 to ensure that the center of the running frame 1 is consistent with the center of the road surface 6, avoid eccentric loading, and ensure the consistency of construction on both sides of the road surface 6. The construction process can be controlled by the detection mechanism 4, and there is no need to lay tracks before construction, thereby simplifying the construction method and greatly improving the construction efficiency.

[0038] The detection mechanism 4 is provided with a distance sensor 41, which can detect the distance from the frame 1 to both sides of the road surface 6. If the construction is on the bridge deck, the distance to the side of the bridge can be measured, which is convenient to use. It should be noted that the distance sensor 41 can be set as an infrared distance sensor.

[0039] In addition, the controller is not marked in the figure. It is a conventional controller on the market. The controller is the central control system of the paving equipment.

[0040] The above-mentioned rack 1 is a rack symmetrically arranged on both sides. When the center of the rack 1 is consistent with the center of the road surface 6, the distances from the rack 1 to both sides of the road surface are equal.

[0041] The above-mentioned paving equipment has strong operability because it does not need to lay tracks. And through the setting of the detection mechanism 4, the position status of the paving equipment can be detected in time. The equipment has a high degree of informatization, which ensures that the bridge deck assembly process is safe and reliable. The detection mechanism 4 transmits the detected signal to the controller, and the controller controls the rotation of the walking mechanism, so that the paving equipment can change with the change of the line direction and can adapt to the construction of the entire line.

[0042] In a specific embodiment, Figure 3As shown, the travel assembly 3 includes a steering mechanism 31 and a travel wheel 32. The detection mechanism 4 transmits the detected signal to the controller, and the controller controls the movement of the steering mechanism 31. The movement of the steering mechanism 31 can change the travel direction of the travel wheel 32. The distance between the travel assembly 3 and the bridges on both sides of the bridge deck is detected by the detection mechanism 4. When the distance between the travel assembly 3 and the bridges on both sides is not equal, the detection mechanism 4 transmits the signal to the controller, and the controller controls the movement of the steering mechanism 31. The movement of the steering mechanism 31 can change the travel direction of the travel wheel 32, and then the posture of the equipment can be adjusted to ensure that the center of the frame 1 is consistent with the center of the road surface 6, avoid eccentric loading, and ensure the consistency of construction on both sides of the road surface 6.

[0043] The travel assembly 3 further includes a wheel train beam 33, a rotating shaft 34 and a wheel train support 35. The travel wheel 32 is mounted on the wheel train support 35, and the travel wheel 32 can rotate as the wheel train support 35 rotates. The wheel train support 35 is connected to the wheel train beam 33 through the rotating shaft 34, and the steering mechanism 31 is connected to the wheel train support 35. The steering mechanism 31 drives the wheel train support 35 to rotate, thereby driving the travel wheel 32 to rotate, and the travel direction of the travel wheel 32 can be changed. A bearing is also provided between the rotating shaft 34 and the wheel train support 35, and the provision of the bearing can facilitate the rotation of the wheel train support 35.

[0044] In addition, the steering mechanism 31 includes a first rod 311 and a second rod 312, wherein the second rod 312 is retractable from the first rod 311; the first rod 311 is fixedly connected to the walking beam 11, and the second rod 312 is fixedly connected to the wheel support 35. The retraction of the second rod 312 can drive the wheel support 35 to rotate; the rotation of the wheel support 35 can drive the walking wheel 32 to rotate, thereby changing the walking direction of the walking wheel 32.

[0045] The above-mentioned steering mechanism 31 can be set as a cylinder or an electric push rod. When set as a cylinder, the steering mechanism 31 includes a driving cylinder and a cylinder support, the cylinder support is installed on the walking beam 11, one end of the driving cylinder is connected to the wheel support 35, and the other end is connected to the cylinder support; then the driving cylinder can drive the wheel support 35 to rotate, and the rotation of the wheel support 35 can drive the walking wheel 32 to rotate, thereby changing the walking direction of the walking wheel 32.

[0046] The above-mentioned traveling assembly 3 further comprises a driving mechanism 36, which is mounted on the wheel train support 35 and is used to drive the traveling wheel 32 to travel. The driving mechanism 36 is connected to the traveling wheel 32 via a gear.

[0047] In a specific embodiment, Figure 2 and 3As shown, the frame 1 includes a walking beam 11, and the walking beam 11 is connected to the wheel train beam 33 through a fixing member 37. Since the walking beam 11 is fixedly connected to the frame 1, a fixing member 37 is provided below the walking beam 11, and holes are opened on the fixing member 37 and the walking beam 11, and then a pin is inserted into the hole to fix the two, so that the wheel train beam 33 can be fixed to the walking beam 11.

[0048] The frame 1 includes two symmetrically arranged columns 12, which are connected to the traveling assembly 3 via the traveling beam 11; the longitudinal section of the column 12 is in an "L" shape. Therefore, the space formed between the two columns 12 can meet the normal passage of the beam transport vehicle 5 and meet the construction requirements of the protective wall.

[0049] In addition, a mounting flange 13 is reserved on the top of the frame 1, and the columns 12 of different structural forms can be replaced by the mounting flange 13 to meet the construction process of the protective wall and the track plate paving.

[0050] The detection mechanism 4 is disposed at the bottom of the column 12 , and the detection mechanism 4 is symmetrically disposed near the edge of the side of the column 12 .

[0051] In another specific embodiment, Figure 5 As shown, the frame 1 includes two symmetrically arranged columns 12, and the columns 12 are connected to the walking assembly 3 through the walking beam 11; the longitudinal section of the column 12 is in a straight line shape. The shape of the column 12 can be determined according to specific usage requirements, and this structure is suitable for the construction requirements of the track plate.

[0052] In a specific embodiment, Figure 1 and 4 As shown, the lifting assembly 2 includes a traveling trolley 21 and a sling 22 . The traveling trolley 21 is connected to the sling 22 and drives the sling 22 to move, and the traveling trolley 21 travels on the top of the frame 1 .

[0053] The hoisting assembly 2 further includes a hoisting mechanism 23, which is used to connect the traveling trolley 21 and the sling 22; the hoisting mechanism 23 includes four hoisting fixed pulleys 231, the sling 22 includes four first fixed pulleys 221, and the traveling trolley 21 includes a second fixed pulley 211; a steel wire rope 232 is wound around the first hoisting fixed pulley 231 and the first first fixed pulley 221, a steel wire rope 232 is wound around the second hoisting fixed pulley 231 and the second first fixed pulley 221, and a steel wire rope 232 is sequentially wound around the third hoisting fixed pulley 231, the third first fixed pulley 221, the second fixed pulley 211, the fourth first fixed pulley 221 and the fourth hoisting fixed pulley 231, so as to hoist the sling 22 under the traveling trolley 21. Stability during the hoisting process is achieved through the principle of three-point balance of four-point hoisting.

[0054] It should be noted that when used for track slab construction, the column 12 is replaced with the track slab column 12, the protective wall hanger 22 is replaced with the track slab hanger 22, and the remaining components are the same as those during the protective wall construction. At this time, the detection mechanism 4 is installed on the running wheel 32 to detect the distance between the running wheel 32 and the protective wall, and then adjusts the posture through the steering mechanism 31 to prevent the running wheel 32 from damaging the protective wall.

[0055] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0056] The above description is only a specific implementation of the present application, so that those skilled in the art can understand or implement the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application.
