Description
Technical field
The utility model is related to it is a kind of be applied to safety protection structure, specifically a kind of quarry tipper loading space that is applied to
Safety lock structure.
Background technology
Mine truck is the key equipment in surface mine exploitation and extensive earthworks, is transported for ore or the earthwork
Defeated professional equipment, have the characteristics that load-carrying is big, operating efficiency is high, residing working environment is severe, and operating mode is complicated.It is mining at present
Truck has the trend developed towards large, hugeization direction, and the requirement to the bearing structure intensity of mine truck is also increasingly
It is harsh.
Quarry tipper is the key equipment in surface mine exploitation and extensive earthworks, is to be used for ore or the earthwork
The professional equipment of transport, have the characteristics that load-carrying is big, operating efficiency is high.Quarry tipper has towards maximization, hugeization at present
The trend of development, the requirement to the bearing structure intensity of quarry tipper are also increasingly harsher.
The loading space weight of electric transmission quarry tipper is all more than more than ten tons, when carrying out quarry tipper maintenance, often
Need to lift the loading space of quarry tipper, to check the part of loading space bottom and part.In engine misses situation
Under, loading space only is supported by elevating ram, loading space may be caused in Action of Gravity Field due to letting out the situation for causing oil cylinder to shrink in oil cylinder
Lower automatic decline.This is breakneck to obtaining maintainer in loading space bottom, may cause serious security incident.
Utility model content
The utility model purpose is to provide a kind of safety protection structure, solves in the progress of the loading space bottom of quarry tipper
Maintenance and during maintenance activity, the problem of loading space caused by being let out in elevating ram declines under gravity, and then effectively ensure
The life security of operating personnel.
To solve the above problems, the technical scheme taken is：One kind is used for quarry tipper loading space safety lock structure, wraps
Safety rope is included, safety joint is equipped with described safety rope both ends, the safety joint of described safety rope one end is fixedly connected
In the aft mount of loading space, the safety joint of the described safety rope other end is fixedly connected on mining dump truck rear-axle shell；
Described safety joint and safety rope are that steel construction, described safety joint and safety rope are formed using integral cast and compacting.
Further, described safety joint is the ears structure provided with pin-and-hole, and use is additionally provided with described safety joint
In on the safety pin being fixed on safety joint in the aft mount and rear axle housing of loading space, the bracket at tail part of described loading space and institute
The hole corresponding with safety pin is equipped with the mining dump truck rear-axle shell stated.
Further, described safety pin, which is provided with, is used to assign locking bolt to prevent safety pin from taking off the locking hole in hole.
Further, the safety rope selects the hoist rope of flexibility high intensity.
Further, lug boss is equipped with the aft mount of described loading space and dumper rear axle housing, with safety pin phase
Corresponding hole is located at described lug boss.
Further, the safety joint, safety rope and safety pin are steel construction.
Beneficial effect caused by the utility model：1st, loading space of the utility model in dumper gives rise to certain angle
Afterwards, safety lock structure is set between the aft mount of loading space and rear axle housing, under can effectively preventing loading space under gravity
Drop, further ensure the safety of container bottom operating personnel；2nd, the safety rope in the utility model and safety joint are integrated
Casting forms, and adds the stability and fastness of safety lock；3rd, the safety rope in the utility model is according to mechanical property requirements
Using high intensity lifting shaped steel wire rope, safety lock structure is born bigger active force, further increase the firm of safety lock
Property.Steel wire rope flexibility is good, can effectively solve the highly asynchronous installation question of packing case lifting, convenient installation.Steel wire rope is strong
Degree is high, and case unit capacity is big, effectively reduces the weight of whole safety lock, makes safety lock installation more convenient.
Brief description of the drawings
Safety lock structure schematic diagram in Fig. 1 the utility model；
Safety lock structure use state figure in Fig. 2 the utility model；
1 safety joint in figure, 2 safety ropes, 3 safety pins.
Embodiment
Explanation is further explained to the utility model with reference to the accompanying drawings and detailed description.
With reference to Fig. 1 and Fig. 2, in order to prevent dumper when detecting loading space lower part, safety caused by oil cylinder shrinks is hidden
Suffer from, one safety lock structure is set in loading space bottom.One kind is used for quarry tipper loading space safety lock structure, including safety rope 2, pacifies
The both ends of full rope 2 are provided with safety joint 1, and the safety joint 1 of the one end of safety rope 2 is fixedly connected in the aft mount of loading space, peace
The safety joint 1 of 2 other ends of full rope is fixedly connected on mining dump truck rear-axle shell；In order to increase the fastness of safety lock, peace
Full joint 1 and safety rope 2 select steel construction, and be integrated cast after suppress and form；Safety lock can be designed as one end and forever may be used
The aft mount or dumper rear axle housing that are fixed on loading space rotated, the other end is fixed during use；It may be designed in
The structure that both ends can freely dismantle from dumper；The tail for safety joint 1 to be fixed on to loading space is additionally provided with safety lock
Safety pin 3 on portion's bearing and rear axle housing, safety joint 1 are the ears structure provided with pin-and-hole, on the bracket at tail part of loading space and ore deposit
With being equipped with the hole corresponding with safety pin 3 on dumper rear axle housing, safety pin 3 through in safety joint 1 and bracket at tail part/after
Safety locking is scheduled on dumper by the hole on axle housing, and the safety pin 3 can be bolt, through pin-and-hole after fixed by nut,
Can be in end set locking hole, both ends are fixed with locking bolt after safety pin 3 passes through pin-and-hole；The utility model can be in the tail of loading space
Lug boss is set on portion's bearing and dumper rear axle housing, safety locking is scheduled on jut.For the power for being born safety lock
Mechanical requirements are more conformed to, both ends and the junction of safety joint 1 of safety rope 2 are necessary for one-piece casting shaping, and safety rope 2 is tool
Standby high intensity and safety rope 2 easy for installation, in light weight, safety rope 2 are made from flexibility high intensity hoist rope.
Because the hydraulic unit and control element of quarry tipper are located at container bottom, need to lift in container in maintenance
Certain altitude is raised to, maintenance personal needs to carry out maintenance work under the container for giving rise to certain altitude.But container
Container is easily caused due to the reason such as unloading in self gravitation and load lifting cylinder to fall, so as to cause life to the maintenance personal of container bottom
It is dangerous.After loading space of the utility model in dumper gives rise to certain angle, between the aft mount of loading space and rear axle housing
Safety lock structure is set, the decline of loading space under gravity can be effectively prevented, further ensure the safety of operating personnel.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and modification can also be made, these change
Enter and also should be regarded as the scope of protection of the utility model with modification.
