Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1 to Figure 3, this support arm being used for fixing forklift door frame comprises connecting portion 10 and is symmetricly set on two operate portions 20 at connecting portion 10 two ends, each operate portions 20 is all vertical with connecting portion 10 to be arranged, connecting portion 10, two operate portions 20 threes are connected as a single entity and are positioned at same plane, two operate portions 20 are respectively equipped with floor 21, the middle part of floor 21 outwards bends and extends to form the vertically disposed arc convex 211 with connecting portion 10, each protruding 211 are all arranged with corresponding operate portions 20 is vertical, run through on protruding 211 and offer mounting hole 212 and two mounting holes 212 are coaxially arranged, mounting hole 212 and connecting portion 10 be arranged in parallel, the circular arc side of protruding 211 offers auxiliary tank 213, the via hole 214 with corresponding mounting hole 212 UNICOM is offered bottom auxiliary tank 213, also knock hole 215 is offered respectively bottom two floors 21.
The doorframe that every one-level door frame of fork truck all be arranged in parallel by two substantially forms, all need in principle to adopt support arm to come firmly to act on, the power of operationally bearing due to the inner upright mounting of fork truck is relatively large, and inner upright mounting is after lifted goods rises one end distance, also can upward movement, this has enough intensity to act on its power with it to support these with regard to needing inner upright mounting.
In prior art, by welding technique many parts are welded on door frame doorframe and form support arm, thus play the effect of firm door frame, strengthen the self-strength of door frame.But there is many uncertain factors in welding process, working accuracy is difficult to reach requirement, task difficulty is large, the quality of door frame finally can be caused not pass a test, and then affect the work efficiency of fork truck.
The utility model adopts the method for casting that support arm is one-body molded, not only solves welding Problems existing, also ensure that the intensity of support arm.When support arm and inner upright mounting are linked together, two floors 21 contact with inner upright mounting respectively, inner upright mounting offers and the corresponding through hole arranged of two mounting holes 212, an adapter shaft can be adopted during installation, this adapter shaft can pass each mounting hole 212 and each through hole, floor 21 and inner upright mounting are linked together, is installed together by whole support arm and inner upright mounting.In addition, also can pass through two minor axises, the mounting hole 212 and the through hole that are each passed through corresponding setting connect floor 21 and inner upright mounting.
It is little that two mounting holes 212 coaxially arrange deviation when can ensure to install, and position is accurate, guarantees that door frame is parallel, does not produce tilt phenomenon.Protruding 211 arrange facilitates offering of mounting hole 212 on the one hand, on the other hand when not affecting floor 21 and working, reduce the volume of floor 21, thus the weight of support arm can be alleviated, avoid producing unnecessary pressure to inner upright mounting, in addition, such design also makes the moulding of whole support arm seem attractive in appearance.
Offering of auxiliary tank 213 provides convenient for offering via hole 214, screw thread can be offered in via hole 214, carry out firmly by screw through the adapter shaft in via hole 214 pairs of mounting holes 212 or minor axis, further guarantee support arm is firmly connected with between inner upright mounting, makes fork truck everything goes well with your work to carry out.Other attaching partss can certainly be adopted according to actual service condition, adapter shaft or minor axis are firmly acted on.When not affecting support arm is firmly connected with inner upright mounting and can also revising with adapting to via hole 214, reach more favourable connection effect.
Arranging of knock hole 215 can first allow support arm and inner upright mounting mutually locate, the connection after being convenient to.
Preferably, operate portions 20 offers arc-shaped curved surface 22, floor 21 is provided with positioning groove 23 away from the side of connecting portion 10 and the junction of arc-shaped curved surface 22, and the bottom of operate portions 20 stretches out and forms projection 24 and one of them side of projection 24 is connected with arc-shaped curved surface 22.
Positioning groove 23 arrange on the one hand can with knock hole 215 with the use of, support arm and inner upright mounting are located more accurate, then be convenient to be close to inner upright mounting on the other hand, reduce the mutual motion between support arm and inner upright mounting, guarantee that both motions are consistent, thus the wearing and tearing that can reduce between support arm and inner upright mounting, delay service life.In addition, the setting of positioning groove 23 also can alleviate the weight of support arm, is conducive to reducing pressure.The setting of arc-shaped curved surface 22 is convenient to form positioning groove 23 and make support arm moulded attractive in appearance further.
When support arm is arranged on inner upright mounting, projection 24 is straight down, the side that projection 24 is connected with arc-shaped curved surface 22 contacts with inner upright mounting, can play a supporting role to inner upright mounting when inner upright mounting is stressed, strengthen the ability to bear of inner upright mounting to a certain extent, be convenient to the related work such as lifting, transport carrying out goods.
Further preferably, the middle part of connecting portion 10 stretch out formed reinforced rib 11.The power that connecting portion 10 bears in support arm is maximum, and the setting of reinforced rib 11 is then the ability to bear in order to strengthen connecting portion 10, also reduces support arm self damage at work as far as possible, guarantee the service life of support arm while ensureing that everything goes well with your work and carrying out.
This support arm being used for fixing forklift door frame can be fastenedly connected by an adapter shaft or two minor axises and inner upright mounting, although whole support arm structure is fairly simple, each structure on support arm is all very meaningful to the work of whole support arm.Whole support arm is handsome in appearance, and has very high intensity, is convenient to widely use.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
