Description
Technical field
The utility model relates to the component be connected that is a kind of and lift truck attachment, refers to a kind of quick change accessory device of loader/forklift truck of long service life especially.
Background technology
Promote a car multiplex period in loader/loader/forklift truck producer, fast replacing device is the selection of a lot of producer.How the connection of quick change bracket and accessory in the market coordinates realization by hook portion and connection bearing pin.And existing most accessory being provided with more a plurality of hook portion, multiple hook portion links up with on the sleeve of bracket (if application number is the forklift truck accessory quick change bracket disclosed in the Chinese utility model patent of 201420118996.1) simultaneously; There is following deficiency in such frame mode: even if there is multiple hook portion, but the contact area of hook portion and sleeve is little, it is large that sleeve bears pressure, in addition, ensure that multiple hook portion is all close with the contact of sleeve, to make sleeve uniform force, just need the requirement on machining accuracy of multiple hook portion very high, processing cost is large.
In addition, the connection of quick change bracket and accessory in the market all adopts the horizontal installation of oil cylinder, such mounting means pin joint limits by swing arm (swing arm lower fulcrum is direct and bracket is hinged) lower fulcrum, from pull bar (rocking arm by pull bar and bracket hinged) close to fulcrum, the arm of force is less, thus bear larger power, make the wearing and tearing connecting bearing pin too large, even cause the premature breakdown of oil cylinder to which increases the use cost of user.
Summary of the invention
The utility model provides a kind of quick change accessory device of loader/forklift truck of long service life, and, sleeve high with the hook portion requirement on machining accuracy overcoming the accessory that existing quick change accessory device exists bears the large problem of pressure.
The utility model adopts following technical scheme:
The quick change accessory device of the loader/forklift truck of long service life, comprises accessory and bracket, bracket respectively with swing arm and rocking arm hinged.The sleeve be connected with accessory that pallet top erection has a horizontal expansion, accessory is provided with a hook portion, and this hook portion is provided with hook groove, and hook groove extends transversely, and above-mentioned sleeve is sheathed in this hook groove.Above-mentioned sleeve two ends are assemblied on above-mentioned bracket respectively by a mount pad, and two mount pads are all in truncated cone-shaped, and two mount pads form a spacing zone, and above-mentioned hook portion is arranged in and this spacing zone, and namely the two ends end face of hook portion is connected with two mount pads respectively.
Further, above-mentioned bracket is fixedly equipped with driving cylinder and is connected bearing pin, and accessory is fixed with and the Connection Block being connected bearing pin and being connected, and Connection Block is located at the Di Yanchu of accessory.This bracket is provided with guide holder, and guide holder is provided with pilot hole, and pilot hole connects the bearing of trend of bearing pin for limiting, this Connection Block is provided with connecting hole, and pilot hole and connecting hole are coaxially arranged.This driving cylinder extends longitudinally, and driving cylinder drives described connection bearing pin longitudinally by described Connection Block or extract by Connection Block.
From the above-mentioned description to the utility model structure; compared to the prior art; the utility model tool has the following advantages: the hook portion of the accessory of quick change accessory device of the present utility model only arranges one; the contact area of the sleeve of itself and bracket is large; and the homogeneity of the processing at an each position of hook groove more easily realizes; hook groove and sleeve compact siro spinning technology, be conducive to the protection of sleeve, increase the service life.
In addition, by changing the bearing of trend of oil cylinder, make the assembly direction connecting bearing pin by laterally changing longitudinal direction into, such vibrational power flow avoids the space constraint connecting the fulcrum that bearing pin is subject to swing arm and pull bar and bracket hinged, and reduce the height of quick change bracket and the pin joint (being namely connected the tie point of bearing pin and mount pad) of quick change accessory, that add mount pad with swing arm and pull bar and the hinged fulcrum of bracket distance, the arm of force is increased, thus reduce the stressed of connection bearing pin, reduce the wearing and tearing connecting bearing pin, reduce the maintenance of equipment, use cost.
Accompanying drawing explanation
Fig. 1 is the decomposition texture schematic diagram of quick change accessory device of the present utility model.
Fig. 2 is the enlarged drawing of the local A in Fig. 1.
Detailed description of the invention
Detailed description of the invention of the present utility model is described with reference to the accompanying drawings.
With reference to Fig. 1, the quick change accessory device of the loader/forklift truck of long service life, comprise accessory 1 and bracket 2, bracket 2 lower fulcrum and swing arm 3 lower fulcrum hinged (as dotted arrow in Fig. 1 indicates), on bracket 2, fulcrum and pull bar 4 hinged (as dotted arrow in Fig. 1 indicates) realize installing, and pull bar 4 is hinged with Rocker arm 5.The sleeve 21 be connected with accessory 1 that bracket 2 top shelf is provided with horizontal expansion, accessory 1 is provided with the hook portion 11 of hooking this sleeve 21.Bracket 2 is fixedly equipped with quick changing oil cylinder 22(and the driving cylinder of two synchronous operations) be connected bearing pin 23, accessory 1 is fixed with and the Connection Block 12 being connected bearing pin 23 and being connected, and Connection Block 12 is located at the Di Yanchu of accessory 1.This bracket 2 is provided with guide holder 24, and guide holder 24 is provided with pilot hole, and pilot hole connects the bearing of trend of bearing pin 23 for limiting, this Connection Block 12 is provided with connecting hole, and during connection status, pilot hole and connecting hole are coaxially arranged.This quick changing oil cylinder 22 extends longitudinally, and quick change drives above-mentioned connection bearing pin 23 longitudinally by above-mentioned Connection Block 12 or extract by Connection Block 12.Quick change accessory 1 device of the present utility model is by changing the bearing of trend of oil cylinder, make the assembly direction connecting bearing pin 23 by laterally changing longitudinal direction into, such vibrational power flow avoids the space constraint connecting the fulcrum that bearing pin 23 is subject to swing arm 3 and pull bar 4 and bracket 2 hinged, and reduce the height of the pin joint (being namely connected the tie point of bearing pin 23 and mount pad 25) of quick change bracket 2 and quick change accessory 1, that add mount pad 25 with swing arm 3 and pull bar 4 fulcrum hinged with bracket 2 distance, the arm of force is increased, thus reduce the stressed of connection bearing pin 23, reduce the wearing and tearing connecting bearing pin 23, the maintenance of minimizing equipment, use cost.
