Description

Technical Field

[0001] The invention belongs to the technical field of power systems, and in particular relates to a 35kV floor-standing trolley anti-dumping and rollover protection device. Background Art

[0002] During the maintenance operation of the 35kV busbar PT trolley, due to the heavy weight of the PT trolley and the forward center of gravity, the trolley guide rail has a certain slope, which can easily lead to rollover. In order to solve the above problems, there are sensor-based detection and alarm devices in the prior art, which monitor the tilt angle of the trolley in real time and issue an alarm when the warning threshold is reached. However, the disadvantage is that it cannot actively prevent the trolley from tipping over. Another type is a herringbone magnetic auxiliary device, which is installed on the two side walls of the switch cabinet. When the trolley moves, the magnetic block will be adsorbed on the guide rail to provide a stable support and guide. The device plays a good protective role and has high reliability. The disadvantage is that the cost of renovating the old 35kV switch cabinet is too high, and the wear of the magnetic block needs to be checked regularly, which has high maintenance costs. Summary of the invention

[0003] The object of the present invention is to provide a 35kV floor-standing trolley anti-dumping and rollover protection device to solve the problems existing in the background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a 35kV floor-standing trolley anti-tipping and rollover protection device, comprising a metal fixing frame, a telescopic safety belt and a latch, the metal fixing frame is hung with a switch cabinet crossbeam, the telescopic safety belt is installed on the metal fixing frame, the latch is fixed on the trolley body, the head of the telescopic safety belt is provided with a fixing part, and the fixing part is connected with the latch.

[0005] Preferably, a round hole buckle is fixed to the upper end of the metal fixing frame, and the head of the retractable safety belt passes through the round hole buckle and is then connected to the latch.

[0006] Preferably, a hook is integrally formed on the upper rear portion of the metal fixing frame.

[0007] Preferably, a baffle is integrally formed on the lower rear portion of the metal fixing frame.

[0008] The beneficial effects of the present invention are as follows: the present invention has a reasonable design structure, can assist operators in pulling out and pushing in the trolley, effectively prevents the equipment from tipping over or overturning, ensures the safety of operators, and improves work efficiency.

[0012] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0013] like Figure 1-3 As shown, a 35kV floor-standing trolley anti-tipping and rollover protection device includes a metal fixing frame 1, a telescopic safety belt 2 and a latch 3. The metal fixing frame is hung with a switch cabinet crossbeam 4. Specifically, a hook 8 is integrally formed on the upper rear side of the metal fixing frame, and the hook is clamped on the switch cabinet crossbeam. A baffle 9 is integrally formed on the lower rear side of the metal fixing frame. The baffle cooperates with the hook to fix the metal fixing frame on the switch cabinet crossbeam. This structure is also easy to disassemble. The telescopic safety belt is installed on the metal fixing frame. In this application, the telescopic safety belt adopts an existing structure, which can be pulled out and automatically retracted. The latch is fixed on the trolley body 5. The head of the telescopic safety belt is provided with a fixing part 6. The fixing part is connected to the latch. The fixing part can be a round hole with the safety belt itself, and the latch is directly inserted into the round hole, or it can be a separate metal part. The safety belt is first fixed together with the fixing part, and then the latch is inserted into the fixing part for easy operation. The structure is designed to be easily connected to the switch cabinet crossbeam, and is tightly fixed to the switch cabinet crossbeam by a metal fixing frame using a mechanical clamping connection.

[0014] Furthermore, in order to facilitate the smoother movement of the head of the safety belt, a round hole buckle 7 is fixed on the upper end of the metal fixing frame, and the head of the telescopic safety belt passes through the round hole buckle and is then connected to the pin. The metal fixing frame is hung by the switch cabinet crossbeam, and the metal fixing frame is connected to the pin on the trolley through the safety belt, so as to achieve the purpose of preventing the trolley from tipping over and rolling over by the safety belt.

[0015] In actual on-site applications, first put on insulating gloves, then hook the metal fixing frame to the middle position of the switch cabinet beam, so that the metal fixing frame and the switch cabinet beam are completely pressed and compacted to complete the fixation. Pull the safety belt to lock the fixing parts with the fixed safety pins installed in advance on the trolley to complete the installation of the device. If the trolley tips over during the process of pulling out or pushing in, the safety belt will be locked immediately to keep the trolley in a safe and stable position to ensure the safety of the operator.

[0016] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
