Description

Pneumatic lifting bridge plate
Technical Field
The utility model relates to a pneumatic lift bridge plate belongs to bridge plate technical field.
Background
The bridge plate is a metal plate with two bearing surfaces, and the bridge plate is used for filling a gap between the platforms and facilitating transportation tools such as trolleys and the like to pass through the gap.
At present, the existing bridge plate is not reasonable enough in structural design, large in size, space-occupying, complex in operation, inconvenient to use and incapable of rapidly lifting the height of the bridge plate, and the use requirements of people cannot be met.
Disclosure of Invention
To the above problem, the to-be-solved technical problem of the utility model is to provide a pneumatic lift bridge plate.
The utility model discloses a pneumatic lift bridge plate, it contains entablature, lower carriage, first pendulum rod, second pendulum rod, cylinder, and entablature and lower carriage parallel arrangement, and be provided with first pendulum rod and second pendulum rod between the both ends of entablature and lower carriage, the upper and lower both ends of first pendulum rod and second pendulum rod respectively with entablature and lower carriage swing joint, install the cylinder in the lower carriage, the one end and the first pendulum rod of cylinder are connected.
Preferably, one side of the lower part of each of the first swing rod and the second swing rod is provided with a stop dog, and the stop dogs on the first swing rod and the second swing rod are attached to the lower rack during operation, so that the swing rods can be limited.
The utility model has the advantages that: its structural design is reasonable, easy operation, and convenient to use switches the flexible height that can go up and down the bridge plate very fast of cylinder, just contracts the cylinder when needs hide the bridge plate, just ejecting with the cylinder when needs bridge plate during operation, has satisfied people's user demand.
Description of the drawings:
for ease of illustration, the invention is described in detail by the following detailed description and accompanying drawings.
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a side view of FIG. 1;
FIG. 3 is a top view of FIG. 1;
FIG. 4 is a schematic view of the usage state of the present invention;
fig. 5 is a schematic structural diagram of a second embodiment.
1-upper beam; 2, lower frame; 3-a first swing link; 4-a second swing link; 5-air cylinder; 6-a stop block; 7-extension rod.
The specific implementation mode is as follows:
the first embodiment is as follows: as shown in fig. 1 to 4, the following technical solutions are adopted in the present embodiment: the upper cross beam 1 and the lower frame 2 are arranged in parallel, a first swing rod 3 and a second swing rod 4 are arranged between the two ends of the upper cross beam 1 and the lower frame 2, the upper end and the lower end of the first swing rod 3 and the lower end of the second swing rod 4 are movably connected with the upper cross beam 1 and the lower frame 2 respectively, the lower frame 2 is provided with the air cylinder 5, and one end of the air cylinder 5 is connected with the first swing rod 3.
And one side of the lower part of each of the first swing rod 3 and the second swing rod 4 is provided with a stop dog 6, and the stop dogs 6 on the first swing rod 3 and the second swing rod 4 are attached to the lower rack 2 during operation, so that the swing rods can be limited.
The second embodiment is as follows: as shown in fig. 5, the present embodiment differs from the first embodiment in that: the lower end of the first swing rod 3 is connected with an extension rod 7, one end of the extension rod 7 is connected with the air cylinder 5, the action point of the air cylinder 5 is arranged below the lower rack 2, and other components and connection relations are the same as those of the first embodiment.
The third concrete implementation mode: the present embodiment differs from the first embodiment in that: the air cylinder 5 is replaced by a hydraulic cylinder, the hydraulic cylinder is used for replacing the air cylinder, and other components and connection relations are the same as those of the first specific embodiment.
The specific embodiment is a four-bar mechanism, and the first swing rod 3 and the second swing rod 4 are driven to rotate left and right by utilizing the expansion and contraction of the air cylinder 5, so that the upper cross beam 1 is forced to move up and down; the cylinder 5 contracts to drive the first swing rod 3 and the second swing rod 4 to swing rightwards, so that the upper cross beam 1 descends, after the cylinder 5 contracts for one stroke, the upper cross beam 1 descends to the lowest point, otherwise, after the cylinder 5 ejects one stroke, the upper cross beam 1 ascends to the highest point, the stop blocks 6 on the first swing rod 3 and the second swing rod 4 are attached to the lower rack 2, a limiting effect can be achieved on the first swing rod 3 and the second swing rod 4, and due to the fact that the first swing rod 3 and the second swing rod 4 deflect leftwards at a small angle, the upper cross beam 1 can bear a large acting force on the upper portion, and therefore the function of a bridge plate is achieved.
This embodiment structural design is reasonable, easy operation, and convenient to use switches the flexible height that can go up and down the bridge plate very fast of cylinder, just contracts the cylinder when needs hide the bridge plate, just ejecting with the cylinder when needs bridge plate during operation, has satisfied people's user demand.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
