Description

Technical Field

[0001] The utility model relates to the field of crawler cranes, in particular to a walking platform and guardrail structure that can be transported along with a main machine. Background Art

[0002] A crawler crane is a truss-jib crane with a crawler chassis. A walkway / gangway is a walkway suspended from the side of the crane structure for personnel to pass through, stand for maintenance, or pass through. A guardrail / handrail is a continuous hand support between two locations.

[0003] Crawler cranes are an important category of lifting machinery. They have the advantages of high lifting performance, load-carrying travel, and adaptability to complex environments. Therefore, they play an important role in the construction of infrastructure, wind power, nuclear power, petrochemicals, etc. On crawler cranes, walkways and guardrails are indispensable components. The walkway fixed support adopts an open notch. During operation, the walkway pin support is inserted into the notch and tightened with bolts from the bottom. The guardrail is installed on the other side of the walkway with bolts. Walkways and guardrails generally need to be removed for long-distance transfers and transported separately. Each walkway weighs more than 30 kilograms, and each disassembly and assembly requires the cooperation of at least two people. In addition, after removal, they need to be placed separately during transportation. During installation, they need to be re-positioned and transported and installed, which requires a lot of manpower and time.

[0004] Therefore, it is necessary to develop a new type of walkway and guardrail structure that can be transported with the main machine to solve the problem of time-consuming and labor-intensive disassembly and assembly of the walkway and guardrail when the crawler crane is transferred. Utility Model Content

[0005] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, the utility model provides a walkway and guardrail structure that can be transported with the main machine, so that the walkway and guardrail can be transported together with the main machine when the crawler crane is transferred, thereby improving the disassembly and assembly efficiency and reducing the transportation protection of the walkway and guardrail.

[0006] Technical solution: The walkway and guardrail structure of the utility model can be transported with the main machine, and is characterized by: comprising a walkway and a guardrail, the walkway is connected to the walkway fixed support through a walkway fixed pin, and the walkway is provided with a tightening device; the guardrail is connected to the walkway through a guardrail fixed pin; the walkway fixed support is a structure of an open notch + two circular holes.

[0007] Wherein, a hole body corresponding to the circular hole on the fixed support of the walkway is opened on the walkway.

[0008] Wherein, the walkway fixing pin shaft is inserted into the hole body of the walkway and the circular hole of the walkway fixing support.

[0009] Wherein, the guardrail is provided with a hole for the guardrail fixing pin to pass through.

[0010] Wherein, the tightening device is a bolt.

[0011] Wherein, the walkway and guardrail are arranged on the crane mainframe.

[0012] Wherein, the crane is a crawler crane.

[0013] Beneficial Effects: Compared with existing technologies, this utility model has the following significant advantages: Through its novel walkway and guardrail structure, the walkway and guardrail can be transported along with the main machine during transportation. This reduces assembly and disassembly effort and reduces the need to find and re-match parts during assembly, resulting in efficient assembly and disassembly. It also avoids the inadequate protection of the walkway and guardrail during bulk transportation, which can lead to bumps and rust. The walkway and guardrail are secured with pins during assembly and disassembly; simply removing the pins allows for flipping and securing, making operation convenient.

[0018] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The utility model discloses a walkway and guardrail structure that can be transported with the main machine, including a walkway 1 and a guardrail 2. The walkway 1 is connected to the walkway fixed support 3 through a walkway fixed pin 4, and the walkway 1 is provided with a tightening device 5; the guardrail 2 is connected to the walkway 1 through a guardrail fixed pin 6; the walkway fixed support 3 is a structure of an open gap + two circular holes.

[0020] The walkway 1 of the present invention has holes corresponding to the circular holes in the walkway fixing support 3. The walkway fixing pin 4 is inserted into the holes in the walkway 1 and the circular holes in the walkway fixing support 3. The guardrail 2 has holes for the guardrail fixing pin 6 to pass through. The tightening device 5 is a bolt. The walkway 1 and guardrail 2 are mounted on a crane. The crane is a crawler crane.

[0021] During operation, the platform fixing support 3 consists of an open notch and two circular holes. During normal operation of the platform 1, the platform fixing pin 4 is inserted into one of the circular holes of the platform fixing support 3 and tightened with bolts from the bottom. The guardrail 2 is installed at the other end of the platform 1 and secured with the guardrail fixing pin 6. To relocate, the platform 1 is flipped upward 90°, and the platform fixing pin 4 is inserted into the hole of the platform 1 and the other circular hole of the platform fixing support 3 to secure the platform 1. The guardrail 2 is removed and installed in the circular hole at the bottom of the platform 1. This allows both the platform 1 and the guardrail 2 to be transported along with the main machine, eliminating the need to remove them for separate transportation.

[0022] The innovation of this utility model lies in the fact that the platform is connected to the mainframe support via a pin. During transport, the platform is rotated 90° via the original fixed pin (the support structure and platform structure can be a notch or a round hole) and secured with another set of round holes and pins. Furthermore, a guardrail transport mounting point is provided below the platform, allowing the guardrail to be fixed to the platform during transport, so that it can be transported with the mainframe.

[0023] This utility model utilizes a novel walkway and guardrail structure, allowing both the walkway and guardrail to be transported along with the mainframe during transport. This reduces assembly and disassembly effort and eliminates the need for re-matching components during assembly, resulting in efficient assembly and disassembly. This also eliminates the risk of the walkway and guardrail being damaged or corroded during bulk transport due to inadequate protection. The walkway and guardrail are secured with pins during assembly and disassembly, allowing for easy flipping and securing by simply removing and installing the pins.
