Description
TECHNICAL FIELD
[0001] The utility model belongs to the safety protection technical field of milling and planing machine, and relates to a safety anti-backup structure of milling and planing machine. BACKGROUND
[0002] Milling and planing machine (also known as road milling and planing machine or cold milling machine) is a kind of mechanical equipment specially used for removing road surface layer, and is widely applied in road maintenance and reconstruction engineering.It can efficiently remove the surface layer of asphalt or concrete pavement in order to carry out subsequent repair, re-paving or other processing.
[0003] When milling and planing machine works, cutter head needs to be lowered so that cutter extends into road surface below a certain distance for milling.After the worker pushes the milling and planing machine to work for a period of time and stops, it is easy to forget to lift the cutter head, so when the worker or other workers stand behind the handrail and start the milling and planing machine again, the cutter is still below the ground, which makes the milling and planing machine have the risk of backup when starting.
[0004] In addition, the worker may misoperate when working normally, for example, the worker misoperates to put it in reverse gear, which will also cause the milling and planing machine to have backup problem.The above two cases will cause the milling and planing machine to retreat and hit the worker, resulting in safety accident. UTILITY MODEL CONTENT
[0005] The utility model aims at solving the above problems, and provides a safety anti-backup structure of milling and planing machine.
[0006] In order to achieve the above purpose, the utility model provides a safety anti-backup structure of milling and planing machine, which comprises:
[0007] Mounting frame, mounted on the bottom frame of milling and planing machine;
[0008] Anti-backup structure, comprising two oppositely arranged anti-backup plates and a connecting rod fixedly connected between the two anti-backup plates, the anti-backup plate has anti-backup tooth structure.
[0009] Further, the mounting frame comprises a middle plate and an ear plate fixedly connected with the middle plate at both ends of the middle plate;
[0010] The middle plate is fixedly installed on the bottom frame of milling and planing machine by screw.
[0011] Further, the anti-backup plate and the ear plate are hinged through hinge shaft.
[0012] The utility model has the advantages of the following:
[0013] The safety anti-retreating structure of the milling and ploughing machine does not have the problem that the staff is hit by the machine when starting the machine and forgetting to raise the cutter head. BRIEF DESCRIPTION OF DRAWINGS
[0014] Figure 1 A structural diagram of a safety anti-retreating structure of a milling and ploughing machine according to an embodiment of the present application is schematically shown.
[0015] Figure 2 An exploded view of a safety anti-retreating structure of a milling and ploughing machine according to an embodiment of the present application is schematically shown.
[0016] The meanings of the reference signs in the drawings are as follows:
[0017] 1, mounting frame; 11, middle plate; 12, ear plate; 2, anti-retreating structure; 3, anti-retreating plate; 4, connecting rod; 5, anti-retreating tooth structure; 6, screw; 7, hinge shaft. DETAILED DESCRIPTION
[0018] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the drawings needed in the embodiments will be briefly introduced as follows. Obviously, the drawings in the following description are only some embodiments of the present application, and other drawings can be obtained by those skilled in the art without creative effort on the basis of these drawings.
[0019] The present application will be described in detail below in combination with the drawings and specific embodiments. The embodiments cannot be described one by one here, but the embodiments of the present application are not limited to the following embodiments.
[0020] In combination with Figure 1 and Figure 2 As shown in the drawings, according to an embodiment of the present application, a safety anti-retreating structure of a milling and ploughing machine is provided, which comprises a mounting frame 1 and an anti-retreating structure 2. The mounting frame 1 comprises a middle plate 11 and ear plates 12 fixedly connected to the middle plate 11 at both ends of the middle plate 11, and the middle plate 11 is fixedly installed on the bottom frame of the milling and ploughing machine by screws 6.
[0021] According to an embodiment of the present application, the anti-retreating structure 2 comprises two oppositely arranged anti-retreating plates 3 and a connecting rod 4 fixedly connected to the two anti-retreating plates 3 between the two anti-retreating plates 3, the anti-retreating plates 3 are hingedly connected to the ear plates 12 by hinge shafts 7, and the anti-retreating plates 3 have anti-retreating tooth structures 5.
[0022] The safety anti-retreating structure of the milling and planing machine can be conveniently installed on the underframe of the milling and planing machine, and since the hinge connection of the anti-retreating plate 3 and the mounting frame 1, the anti-retreating plate 3 can be lowered to make the anti-retreating tooth structure 5 contact the ground, and when the milling and planing machine walks previously, since the hinge connection of the anti-retreating plate 3 and the mounting frame 1, normal walking will not be affected. When retreating, the anti-retreating tooth structure 5 is clamped into the ground, so that the milling and planing machine cannot retreat, thereby effectively avoiding the problem that the milling and planing machine retreats and collides with the staff when the cutter head is forgotten to be raised and the machine is started, or avoiding the problem that the milling and planing machine collides with the staff due to the staff's misoperation of hanging the reverse gear. When the milling and planing machine needs to retreat, the anti-retreating plate 3 can be folded down.
[0023] The above merely describes one embodiment of the utility model and is not used to limit the utility model. For those skilled in the art, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
