Description
Technical field
The invention belongs to frame for movement processing safety design field.
Background technology
At present, certain the type vehicle needs being made up of equipment such as chassis, equipment shelter and antenna elevating towers shelter top install a upset platform, be fixed on shelter top during transport, when it is desired to be used, from shelter flip-top to antenna elevating tower on, in order to personnel keep in repair.Upset land lengths is 1600mm, weight about 30kg, and barycenter is positioned at its geometric center, utilizes rotating shaft to be connect by lower margin peace table-hinges, and platform rotates around the shaft, it is achieved upset, turning torque is 240N m.By maintenance platform be turned to be 30 ° with ground level angle time as a example by, calculate by operating physical force 120N, operator need the position with crouching appearance grip distance rotating shaft 400mm, it is steady that guarantee overturns, the gravity motion of people pushes up outer overhead positions to cabin, and shelter top is about 3500mm away from ground level, extremely dangerous.In order to ensure the safety of operator, need a kind of operating mechanism of design, it is ensured that in the range of operator are always positioned at top, cabin in operation, and switching process is steadily, accurately.
Summary of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of operating mechanism, is arranged on upset platform side, it can be ensured that in the range of operator are always positioned at top, cabin in operation.
The technical solution adopted for the present invention to solve the technical problems is: include operating handle and fast lockign apparatus, and described fast lockign apparatus includes location dish and rotation lock；Described location dish is a semicircular steel plate, is connected with platform, and operation handle one end is hinged on the dish center of circle, location, and location dish has hole, two location, and hole, two location is mutually perpendicular to the line in the dish center of circle, location；Described rotation lock includes handle, lock box, dead bolt and spring, described lock box is arranged on operation handle, has through hole, and the end face of through hole one end tilts with through-bore axis, and on the lock box wall of inclined end face, having two locating slots, two locating slots differ with the distance of the through hole other end；Dead bolt is installed in through-holes, dead bolt one end and handle pin joint, handle can rotate and fall within two locating slots respectively, when handle falls within a locating slot, the dead bolt other end stretches out through hole under the action of the spring, enter in the hole, location of location dish, when handle falls within another groove, in dead bolt retraction through hole.
The invention has the beneficial effects as follows: fully meet usability and the security requirement of upset platform, in switching process, with antenna elevating tower overlap joint steadily, accurately, operation arm pivot post and upset platform rotating shaft distance 140mm, in the range of operator are always positioned at top, cabin in operation.Increasing the arm of force (arm of force about 1168mm after second positioning) by operation handle, maximum operating physical force is not more than 40N, significantly reduces the labor intensity of operator.

Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings, and the present invention includes but are not limited to following embodiment.
The whole operating process of the present invention is as shown in Figure 1, including procedure below: first, operation handle is connected as an entirety with platform, rotate up about 90 ° (pushing up the most in vertical state with cabin), after fast lockign apparatus is unlocked, operation handle opposed platforms reversely rotates 90 ° and to the second position location and relocks, again operation handle is rotated up and platform smoothly can be turned on antenna elevating tower, operation handle is final and cabin is pushed up in vertical state, operator can complete whole operating process all the time in the range of cabin is pushed up, ensure that the safety of operation.
The present invention mainly by platform, operation handle, fast lockign apparatus etc. three part constitute.Outward appearance and primary structure are as shown in Figure 2.
Fast lockign apparatus is formed with rotation lock two parts by positioning dish.
Location dish is a semicircular steel plate, is welded as a whole with the housing of platform, as shown in Figure 3.Hole, a location it is each provided with, for being connected with the dead bolt of rotation lock two position locations.
The structure of rotation lock is as shown in Figure 4.Handle and dead bolt are integrated by being fixedly connected of pin, lock box right-hand member be equipped with locating slot, for handle and the location of dead bolt at two up and down.Handle rotates upward along the inclined-plane of lock box right-hand member, and dead bolt stretches out under the thrust of spring, and when being rotated in place in groove positioned over, dead bolt stretches out and puts in place；Handle rotates downwards along inclined-plane, and compression spring also drives dead bolt to retract, and when being rotated in place in the locating slot of lower section, dead bolt is retracted and put in place.Rotation lock is connected as one with operation handle by screw.
By the locking between rotation lock and the location dish of fast lockign apparatus and unblock, it is possible to quickly realize the locking between platform and operation handle and unblock.
The present invention, with the development of certain model special vehicle, through updating, is applied in multiple projects.The present invention, in implementation process, should carry out mechanical analysis, each bearing member is carried out Calculation of rigidity, it is desirable to safety coefficient is more than 3.
The present invention, in implementation process, should also be noted that problems with:
A) all parts all use metal material, and its surface should carry out corresponding preservative treatment according to using environmental requirement；
B) moving part such as rotating shaft and rotation lock need to periodically be coated with grease.
Operational approach of the present invention is as follows:
A) upset platform is freed with the fixing of shelter；
B) checking that operation handle should be reliable with the locking of location dish, operation handle is flipped up 90 ° with platform entirety；
C) hold up steady platform, maintain position of platform.Rotate rotation lock, free the locking of operation handle and location dish.Operation handle reversely rotates 90 °, rotates lock and is locked with location dish by operation handle, completes second positioning；
D) again operation handle is rotated up 90 °, one end of platform is smoothly and precisely overlapped with antenna elevating tower；
E) antenna maintenance work is carried out；
F), after maintenance work, operation handle reversely rotates 90 °, holds up steady platform, maintains position of platform.Rotate rotation lock, free the locking of operation handle and location dish.Operation handle rotate up 90 ° to and platform parallel, rotate rotation lock will operation handle and the locking of location dish, operation handle downwardly turns over 90 ° with platform entirety, is placed horizontally at top, cabin；
G) upset platform is reliably fixed with shelter.
Through overtesting and the application verification in multiple projects, the present invention is easy to operate, reduces product labor intensity in switching process, it is ensured that the safety in eminence upset operation.
