Description

TECHNICAL FIELD

[0001] The present application relates to the field of logistics and warehousing, and in particular provides a special device for applying bottom safety protection to dumping and / or overturning equipment. BACKGROUND

[0002] At present, various automatic transfer equipment is usually used in the sorting site of e-commerce and express industry to cooperate with on-site personnel to implement large-batch goods transfer processing and in-out warehouse operation. For example, containers used in logistics transfer sites include mixed loading cages or material boxes with trays at the bottom. In order to improve the efficiency of centralized transfer, equipment specially used for dumping of cages or large-specification material boxes is correspondingly configured.

[0003] Automatic goods dumping equipment is mainly used for rapid unloading of goods, and has a significant advantage when handling cage or container goods, such as shaking off goods by overturning the cage or separating different types of goods. However, while continuously improving the core function, there are also safety risks in operation, such as goods falling or personnel being crushed due to improper operation when the cage is overturned. In addition, there is also a risk of personnel being crushed and injured during equipment maintenance due to the lack of protective measures.

[0004] The prior art commonly relies on static protective devices such as protective fences and safety doors, which cannot monitor personnel dynamics in real time and are more likely to cause accidents due to misoperation or equipment failure. If the manual judgment method of observing the dangerous area by the operator is relied on, there is a problem of lag, especially in high-intensity operations, which can easily lead to a delayed response.

[0005] Therefore, the present application is proposed. SUMMARY

[0006] The present application provides a safety protection device for overturning equipment, which actively and intelligently prevents and controls the problems existing in the prior art, and builds a multi-layer protection system including intelligent monitoring, automatic shutdown and mechanical protection structure, thereby achieving the purpose of significantly reducing the risk of accidents and improving the safety efficiency of operation.

[0007] To achieve the above design purpose, the safety protection device for overturning equipment comprises left and right protective nets connected to each other, and a group of safety support assemblies are symmetrically arranged on the left and right protective nets respectively. During the operation of the overturning equipment, the two groups of safety support assemblies respectively extend from one side of the left and right protective nets and move to the vertical below the overturning equipment.

[0008] Further, the safety support assembly comprises a fixed seat and a safety support rod. The two ends of the fixed seat are fixedly connected to the left or right protective net, the bottom of the safety support rod is hingedly connected to the left or right protective net, and the top end of the safety support rod can penetrate through the left or right protective net and extend into the area enclosed by the left and right protective nets.

[0009] Further, one end of the mobile telescopic rod is hinged to the safety support rod, and the other end penetrates through the through slot on the fixing seat; a set of joint blocking pin shafts are arranged on the mobile telescopic rod, and a set of pin shaft fixing grooves are arranged on the fixing seat, and after the mobile telescopic rod is turned to the working position, the joint blocking pin shafts are embedded into the pin shaft fixing grooves.

[0010] Further, a sensor bracket is arranged on the fixing seat, and a first proximity switch sensor and a second proximity switch sensor are arranged in pairs at both ends of the sensor bracket.

[0011] Further, a locking knob is screwed on the side of the fixing seat, and the inner end of the locking knob can be screwed into the inside of the fixing seat and pressed against the mobile telescopic rod.

[0012] Further, operation switches for starting safety detection and alarm function and safety grating for dynamically detecting whether there is personnel or equipment entering the area surrounded by the left guard net and the right guard net are arranged on the sides of the left guard net and the right guard net respectively.

[0013] In summary, the safety protection device for the turnover equipment described in the present application has the following advantages:

[0014] 1. The safety grating is used to realize dynamic detection of the dangerous area of the equipment, and the emergency stop is triggered as soon as there is a hidden danger in the operation, so that the overall safety factor is high and the degree of automation is high.

[0015] 2. The mechanical support assembly is added, which can be actively extended to support the turnover equipment during equipment maintenance, thereby maximizing the prevention of mechanical accidents. BRIEF DESCRIPTION OF DRAWINGS
