Abstract
The utility model discloses a buffering-fixing device of a reduction box. The buffering-fixing device is provided to overcome the defects that the reduction box of an existing lifting equipment traveling mechanism magnetic brake is connected with a lifting equipment traveling mechanism table top through a hinge, attrition for a hinged hole and a hinged shaft after an impact enables the reduction box to be damaged and enables braking force to be reduced. The buffering-fixing device comprises a fixing seat of the reduction box and a lower support seat, the upper end of a buffer draw rod is connected with the fixing seat, the nail-shaped head of the buffer draw rod is arranged inside a cylinder-shaped connection rod, and a lower portion of the cylinder type connection rod is connected with the lower support seat. Elastic rubber rings are arranged above and below the nail-shaped head inside the cylinder-shaped connection rod. The reduction box and the traveling mechanism table top are connected together by the buffer draw rod through the cylinder-shaped connection rod and an upper draw rod and a lower draw rod. When reaction force produced by equipment vibrating acts on the elastic rubber rings, shear attrition between a shaft and a hole of a hinge connection in traditional design is avoided, damage for the reduction box and a brake because of the impact is eliminated completely, and safety performance of equipment is improved.

Background technique
Be widely used on the traveller of large lifting equipment of port and pier, current collection machine, break and speed reducer three are the speed reducer of one, are commonly called as three-in-one speed reducer, have compact structure, and cost is low, and it is simple that adjustment is installed, the advantage of good braking effect.But because said speed reducer adopts electromagnetic brake; Walking at equipment is started, is stopped; Or rotation starting, when stopping; Its reaction force is released on the traveller speed reducer and can produces the damage power of impacting, and it is fixing that therefore traditional design is made buffering with speed reducer usually, promptly be designed to the traveller table top between have hinge to be connected and ream the interior fixing device of being with flexible rubber ring.Though the said fixing Design of device has certain buffering fixation, along with the fraising of hinge connector, the wearing and tearing of hinge, impact will further strengthen; Gently then cause its flexible rubber ring to damage, the brake shoe wearing and tearing, heavy then cause its speed reducer internal gear accelerated wear test; Even the table top of speed reducer casing and crane gear collides; Cause speed reducer crackle damage, serious braking force is reduced, thereby have great potential safety hazard; This point shows particularly outstandingly in the crane gear of being engaged in rotary operation that with the gantry crane is representative.
Summary of the invention
The utility model technical problem to be solved is; The traveller that overcomes the existing technology crane gear adopts the speed reducer of electromagnetic brake; And it is fixing to make buffering with the hinge connector of band flexible rubber ring between the traveller table top of crane gear, and the back that is hit is to the fraising of link, the wearing and tearing of hinge, and impact force can further strengthen; Can cause speed reducer damage even cause braking force to reduce and have the shortcoming of great potential safety hazard, a kind of buffering fixing device of speed reducer is provided.
In order to solve the problems referred to above that existing technology exists; The utility model is to adopt following technical proposals to realize: the buffering fixing device of speed reducer comprises: the fixed base that is installed in speed reducer one side; Be positioned at the undersetting on the table top of crane travelling gear under the fixed base; The upper end of following closely the buffering pull bar of font is fixedly connected with fixed base, and the nail prefix of buffering pull bar is installed in the vertical tubular connecting rod, and the lower open end of tubular connecting rod is fixedly connected with undersetting; About the nail prefix in the tubular connecting rod, be separately installed with a plurality of parallel flexible rubber rings.
The utility model also has following technical characteristics:
The mounting structure of said tubular connecting rod is, the said undersetting direction of upper connecting rod subtend is fixed on the said fixed base of speed reducer, and the lower end of upper connecting rod is fixedly connected with the buffering pull bar of following closely font; The body of rod of buffering pull bar passes the end of the tubular connecting rod of the said undersetting direction of opening subtend; The nail prefix of its underpart can move up and down by relative tubular connecting rod in the tubular connecting rod; Be positioned at said nail prefix tubular connecting rod up and down, a plurality of flexible rubber rings be installed along the endoporus direction of tubular connecting rod is parallel; Be fixed on the lower link top on said undersetting top, be fixedly connected with the cylindrical openings end of tubular connecting rod;
The lower end of said upper connecting rod is installed with the mounting type of following closely font buffering pull bar, and the body of rod end of following closely font buffering pull bar is provided with outside thread, and said outside thread is screwed in the inner bolt hole of said upper connecting rod lower end;
On the said outside thread body of rod of said buffering pull bar, be screwed with adjusting nut;
The mounting type that the top of said lower link is fixed on the cylindrical openings end of tubular connecting rod is; The upper end body of rod of lower link is inserted in the cylindrical openings of tubular connecting rod; Block the flexible rubber ring of installing in it, horizontal bearing pin passes the cylindrical openings end of connecting rod and fixes with the upper end of its interior lower link of installing;
The cross section of said flexible rubber ring is circular;
The cross section of said flexible rubber ring is square.
The advantage and the good effect of the utility model be because between speed reducer and traveller table top, flexible cushion rubber be installed in buffering pull bar nail prefix about, be positioned at the inside of tubular connecting rod; The buffering pull bar links together speed reducer and traveller table top again through tubular connecting rod and last lower link, when equipment starts, stops in walking; Or rotation starting, when stopping; The reaction force that vibration produces is an axial force to the impact force of buffering pull bar, all acts on the flexible rubber ring that the buffering pull bar installs up and down, is absorbed by flexible rubber ring then; Make the impact force of crane gear when starting and stopping reduce to minimum; The base designs that has changed former design speed reducer have door assembly with hinge and glass in right hand and left connect in flexible rubber ring receive force direction, by radially shearing force change into axial draw, pressure, speed reducer is reached do not have in running impact, non-maintaining state; Do not influence the normal operation of deceleration system and braking system fully; Avoided the hinge of traditional design to connect the shearing wearing and tearing between axis and the hole, thoroughly eliminated, fundamentally improved the usage safety performance of equipment because of impact brings the damage to speed reducer, break.
