Description

Technical Field

[0001] The utility model relates to a mobile truss vehicle for installing a prefabricated guardrail, belonging to the technical field of highway construction equipment. Background Art

[0002] In highway construction, especially in highway construction, prefabricated guardrails need to be installed on the roadside and in the middle. New Jersey guardrails are used on highways. New Jersey guardrails are used to separate lanes on highways. New Jersey guardrails are about 90-150 cm high, made of grouting concrete, and the weight of a single unit can reach 1,000 kg. New Jersey guardrails can be prefabricated first, and then installed after the pavement base is completed, which greatly shortens the construction period and facilitates operation.

[0003] Since the New Jersey guardrail is heavy, it is very inconvenient to install. Traditional equipment is less efficient in installing New Jersey guardrails. Utility Model Content

[0004] The purpose of the utility model is to provide a mobile gantry vehicle for installing a prefabricated guardrail to solve the above technical problems and improve the installation efficiency of the New Jersey guardrail.

[0008] A further improvement of the technical solution of the utility model is as follows: the overhead travelling mechanism comprises an overhead travelling frame, and a plurality of synchronous wheels are arranged at the lower end of the overhead travelling frame.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front end", "rear end", "two ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0022] The utility model is a mobile gantry truck for installing a prefabricated guardrail, which is used when installing a prefabricated guardrail, such as when installing a New Jersey guardrail. The device is mainly used to hoist the prefabricated guardrail to a predetermined position.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, the equipment mainly includes a main vehicle traveling mechanism, a crane traveling mechanism and a lifting mechanism. Among them, the main vehicle traveling mechanism is the main traveling part of the equipment. Usually, the main vehicle traveling mechanism includes a traveling truss 1, and a plurality of traveling wheels 4 are arranged at the lower end of the traveling truss 1. The traveling wheels 4 of the traveling truss 1 are arranged on both sides and can be synchronized; they can also be electrically traveled on one side to adjust the overall direction, especially when curve travel is required.

[0024] The main vehicle travel mechanism usually uses four active differential motors, which can effectively solve the problem of curve turning. Taking the direction of the road as the longitudinal direction, the main vehicle travel mechanism walks longitudinally. If the road has a curve, it can adapt very well.

[0025] The overhead crane travel mechanism is set on the main vehicle travel mechanism, and the lifting mechanism is set on the overhead crane travel mechanism. The overhead crane travel mechanism drives the lifting mechanism to move horizontally. The lifting mechanism is used to lift and install the prefabricated guardrail. Multiple sets of overhead crane travel mechanisms can be set on each main vehicle travel mechanism, and generally two sets of overhead crane travel mechanisms are set.

[0026] The lifting mechanism can perform fine-tuning walking on the overhead traveling mechanism, and the fine-tuning walking direction of the lifting mechanism can achieve horizontal and vertical fine-tuning. The lifting mechanism performs fine-tuning walking to accurately install the prefabricated guardrail to the predetermined position, and can effectively control the installation seam of the prefabricated New Jersey guardrail.

[0027] In a specific implementation, preferably, the crane travel mechanism includes a crane frame 2, which is a structure spanning the travel truss 1. Generally, two sets of crane frames 2 are provided, and synchronous wheels 6 are provided at the lower ends of the two sets of crane frames 2, a total of four synchronous wheels 6, and a driving motor is provided for power drive. The crane travel mechanism moves on the travel truss 1, and the four synchronous wheels 6 ensure that the crane frame 2 moves synchronously. An anti-derailing device is installed inside the synchronous wheel 6 of the crane travel mechanism, and an infrared or mechanical limiter is installed at the specified end, and a block is added to prevent overtracking.

[0028] like Figure 2 As shown, two groups of lifting mechanisms are arranged on the overhead traveling mechanism. The lifting mechanism comprises a lifting mechanism traveling frame 9 and a hoist 3 arranged on the lifting mechanism traveling frame 9. The lifting mechanism traveling frame 9 comprises two span beams, and synchronous wheels 7 capable of synchronous movement are arranged at the ends of the two span beams. Two hoists 3 are preferably arranged in each group of lifting mechanisms, and the same prefabricated guardrail is lifted and hoisted by these two groups of hoists 3 to ensure stability. During the lifting operation, the two groups of hoists 3 are controlled by the control system to maintain synchronous lifting.

[0029] Furthermore, the two groups of hoists 3 have synchronous wheels 3 8, which can make the two groups of hoists 3 move synchronously on the hoisting mechanism running frame. The synchronous wheels 2 7 of the hoisting mechanism running frame 9 of the hoisting mechanism are adjusted horizontally, and the synchronous wheels 3 8 of the hoist 3 are adjusted longitudinally, so as to achieve accurate adjustment of the position of the prefabricated guardrail. Figure 1 In the process, a lifting mechanism lifts the prefabricated guardrail from the truck to the installation location.

[0030] The walking truss 1 spans the middle area of ​​the highway in the horizontal direction. The longitudinal span of the walking truss 1 is set at 8-12m. After the prefabricated guardrails in the longitudinal span are installed, the walking truss moves forward to install the prefabricated guardrails in the next area.

[0031] The lifting mechanism 3 generally directly uses a winch or an electric hoist.

[0032] The driving parts of the entire vehicle use electricity as the power source, so a diesel generator set is required to power the entire vehicle.

[0033] The utility model can realize the mechanized lifting and installation of the prefabricated guardrail, improve the work efficiency, and can accurately install the prefabricated guardrail to a predetermined position through precise adjustment of the lateral and longitudinal movements, thereby ensuring the construction effect.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
