Abstract
The utility model provides a platform car lifting device, which comprises a main platform, a mounting seat, a front arm, a rear arm, a supporting oil cylinder, a point A, a point B, a point C, a point D, a point E and a point F. According to the technical scheme of the utility model, the entire platform car lifting device is mainly composed of the mounting seat, the front arm, the rear arm, the supporting oil cylinder, connection pins at all joints of the device, and the like. The point F is in the form of bolt connection and the point E is in the form of pin connection. The point E, the point C and the point D are respectively in the form of pin connection. The installation point D is not in the connecting line between the upper and lower end through holes of the front arm. That is to say, the installation point D is positioned between the point C and the point E while not in the central connecting line thereof. The point B, the point A and the point C are respectively in the form of pin connection, wherein the point B is positioned between the point A and the point C. The two ends of all the connection pins are provided with threaded through holes, thereby facilitating the installation of bolts. Meanwhile, the reciprocating movements of the connection pins along the axial direction during the elevating process of the arms along the up-and-down direction can be avoided.
Description
Technical field
The present invention relates to a kind of lifting device, refer to especially a kind of platform truck lifting device.
Background technology
At present, existing platform truck lifting device exist complex structure, oversize, difficulty or high in cost of production phenomenon are installed, economic benefit is bad, to user, brings inconvenience.
Summary of the invention
The object of this invention is to provide a kind of platform truck lifting device, from following 2 principles, solved this defect: for overcome existing platform truck lifting device complex structure, oversize, difficulty or high in cost of production phenomenon be installed.
In order to achieve the above object, the invention provides following technical scheme:
A platform truck lifting device, comprising: main platform, mount pad, forearm, rear wall, support cylinder, A point, B point, C point, D point, E point and F point.Mount pad is connected with main platform; F point is located on mount pad and main platform point of connection; Mount pad is located at one end of forearm; Mount pad is connected with forearm by E point; E point is located on the point of connection of mount pad and forearm; Forearm is connected with postbrachium by C point; C point is located on the point of connection of forearm and postbrachium; Forearm is connected with support cylinder by D point; D point is located on the point of connection of support cylinder and forearm; Support cylinder is connected by B point with postbrachium; B point is located on the point of connection of support cylinder and rear wall; Postbrachium one end is provided with A point; A point is located at one end of postbrachium.
In invention, whole platform car owner platform lifting device is mainly comprised of connection bearing pin of mount pad, forearm, postbrachium, support cylinder and each joint etc.F point is bolt connection, and E point is that bearing pin connects.C point, D point are bearing pin and connect.D point is not on the line at through hole center, the upper and lower two ends of forearm, and D point is between 2 of C, E and not therein on heart line.B point is bearing pin connection.A point, C point is that bearing pin connects, and B point is installed at 2 between A, C.All there is tapped through hole at two ends on all connection bearing pins, are convenient to hold-down bolt, the bearing pin that prevents each junction end float misalignment back and forth in arm oscilaltion.
The invention has the beneficial effects as follows: simple in structure, for convenience detach and installation, bearing force is strong, simple to operate, can bring good economic benefit.
Accompanying drawing explanation
Fig. 1 is that a kind of oil cylinder of platform truck lifting device stretches out structure graph.
Fig. 2 is a kind of oil cylinder retracted state constructional drawing of platform truck lifting device.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
As Fig. 1 and Fig. 2 and as shown in, a kind of platform truck lifting device, comprising: main platform 1, mount pad 2, forearm 3, rear wall 4, support cylinder 5, A point 6, B point 7, C point 8, D point 9, E point 10 and F point 11.Mount pad 2 is connected with main platform 1; F point 11 is located on mount pad 2 and main platform 1 point of connection; Mount pad 2 is located at one end of forearm 3; Mount pad 2 is connected with forearm by E point 10; E point 10 is located on the point of connection of mount pad 2 and forearm 3; Forearm 3 is connected with postbrachium 4 by C point 8; C point 8 is located on the point of connection of forearm 3 and postbrachium 4; Forearm 3 is connected with support cylinder 5 by D point 9; D point 9 is located on the point of connection of support cylinder 5 and forearm 3; Support cylinder 5 is connected by B point 7 with postbrachium 4; B point 7 is located on the point of connection of support cylinder 5 and rear wall 4; Postbrachium 4 one end are provided with A point 6; A point 6 is located at one end of postbrachium 4.
The principle of work of above-mentioned a kind of platform truck lifting device is: the oscilaltion of main platform 1 is mainly stretched out and gets control back by the piston rod of support cylinder 5, when main platform need to rise, the piston rod of support cylinder 5 stretches out, and drives opening of forearm 3 and postbrachium 4, and then main platform 1 rises; When main platform 1 need to decline, the piston rod of support cylinder 5 is regained, and drives the closure of forearm 3 and postbrachium 4, and then main platform 1 declines.
According to above-mentioned principle of work: in invention, whole platform car owner platform lifting device is mainly comprised of connection bearing pin of mount pad 1, forearm 3, postbrachium 4, support cylinder 5 and each joint etc.F point 11 is bolt connection, and E point 10 is that bearing pin connects.E point 10, C point 8, D point 9 are bearing pin and connect.D point 9 is not on the line at forearm through hole center in two ends Shang Xia 3, and D point 9 is between 2 of C, E and not therein on heart line.B point 7 is bearing pin connection.A point 6, C point 8 is that bearing pin connects, and B point 7 is between 2 of A, C.All there is tapped through hole at two ends on all connection bearing pins, are convenient to hold-down bolt, the bearing pin that prevents each junction end float misalignment back and forth in forearm 3 and postbrachium 4 oscilaltions.
The invention has the beneficial effects as follows: simple in structure, for convenience detach and installation, bearing force is strong, simple to operate, can bring good economic benefit.
