Abstract
The utility model relates to the top proof spacing apparatus of an elevating poppet head, which can be arranged at the bottom of a poppet. A lead limit switch of the utility model is arranged on an installing frame, and the on-off state of a switch knob of the lead limit switch is controlled by a stopper arranged on a steel cable. Two symmetrical half cylinders of which the middle parts are respectively provided with a circular arc-shaped steel wire groove which is equal to the half circle of the steel cable are fixed by two or more screws which are close to the both sides of the steel wire groove. The utility model has the advantages of simple structure, convenient fabrication, easy installation and high safety; when elevating, the top proof spacing apparatus of an elevating poppet head is top proof. The top proof spacing apparatus of an elevating poppet head is suitable for high multivariant aloft work, especially building trades for building.
Description
A kind of anti-inhibiting device of rushing to summit that relates in the derrick lifting winch is suitable for using in the aloft work highly changeable on the building ground especially.
At present, lifting position in the derrick lifting winch that uses on the building ground is controlled by two-direction switch, this needs the operating personal ideological plane to concentrate, and the carelessness accident of will rushing to summit is arranged slightly, and it is disconnected to cause steel rope to jump, hanging indigo plant falls, serious consequences such as personal casualty, for this reason, the someone imagined and adorned a distance caging device at the top of derrick, hang indigo plant when being raised to the derrick terminal when what promote, stop automatically rising.The shortcoming that inhibiting device is located at crown is that inconvenience is installed; Derrick will raise along with the rising of the building of being built, every rising one less important inhibiting device of reinstalling, and also each the rising wanted the jumper line; Must check whether limit switch is reliable before the operation, must often go very inconvenient like this to the top.The purpose of this utility model is that design a kind ofly can overcome above-mentioned shortcoming, and is simple in structure, easily manufactured, the anti-inhibiting device of rushing to summit of derrick lifting that easy, safe and reliable limit switch can be contained in the derrick bottom is installed.
Details are as follows in conjunction with the accompanying drawings for structure of the present utility model:
Fig. 1. the constructional drawing of the anti-inhibiting device of rushing to summit of derrick lifting;
Fig. 2. the A of the anti-inhibiting device of rushing to summit of derrick lifting is to figure;
Fig. 3 .A is to the birds-eye view of figure;
Fig. 4. the anti-scheme drawing of inhibiting device when elevator is not worked of rushing to summit of derrick lifting;
Fig. 5. the derrick lifting is anti-, and the inhibiting device of rushing to summit is hanging the scheme drawing of indigo plant when being raised to terminal.
(1) lead limit switch (2) shifter bar (3) erecting frame
(4) electrical equipment control cable (5) block (6) screw
(7) steel rope (8) steel wire rope groove (9) guide wheel (10) hangs indigo plant
The anti-inhibiting device of rushing to summit of derrick lifting is made up of lead limit switch (1), erecting frame (3) and block (5).Lead limit switch (1) is contained on the erecting frame (3), and block (5) is by two symmetries and middle respectively have a semicylinder that waits the circular arc steel wire trough (8) of what steel rope semicircle to fix by the screw more than two or two (6) of steel wire trough two sides and form.During use, the erecting frame (3) that lead limit switch is housed is fixed in the derrick bottom, and block (5) places on the steel rope (7) of derrick side, and steel rope is clamped in two cylindrical steel wire troughs (8) of block (5) by screw (6).Whether the on off state of the shifter bar (2) of lead limit switch (1) collides it by block (5) is decided, during lift winch work, along with steel rope slides in guide wheel (9), hang indigo plant when rising gradually, stop location descends thereupon, when block drops to shifter bar (2) with lead limit switch when colliding, shifter bar is in "off" state, thereby make the electrical equipment control cable in the lead limit switch send electric signal, the derrick elevator is topped out automatically, if the two does not collide, then shifter bar (2) is in "open" state, and elevator continues to rise.The derrick of differing heights, the position that block is contained on the steel rope is also different, shown in Fig. 4 is to hang indigo plant when being raised to terminal when the derrick elevator, the position of block on steel rope should just collide with the lead limit switch that is contained in the derrick bottom, shown in Figure 3 is to get back to ground when hanging indigo plant, when elevator is not worked, the position of block.The block of cylindrical structure can make steel rope also can guarantee with lead limit switch good collision opportunity is arranged at time rotational.
The generation of the phenomenon of rushing to summit when the anti-spacing stroke apparatus of rushing to summit of this structure has prevented the elevator rising, improved degree safe in utilization, this apparatus structure is simple, easy for installation, when rising layer, derrick only needs the manual block screw that unclamps on ground, readjusting the installation site of block on steel rope gets final product, and needn't the shift motion limit switch, cable also can be fixed, the reliable in action of checking inhibiting device is also very convenient, so this device is suitable for using when indigo plant is hung in lifting in the highly changeable aloft work especially.
For an embodiment:
The anti-spacing stroke apparatus of rushing to summit of the derrick lifting that to do a steel rope be φ 13, limit switch is selected L * 19-121 type for use, erecting frame is with an angle steel shelf, it and derrick bottom is with screw or be welded to connect, block respectively is whittled into bevelled semicylinder by the upper and lower side of two symmetries to be formed with four screw retention, and middle steel wire trough is the half slot of φ 13.
Claims (1)
1, the anti-inhibiting device of rushing to summit of a kind of derrick lifting, form by lead limit switch (1), erecting frame (3) and block (5), it is characterized in that lead limit switch (1) is contained on the erecting frame (3), block (5) is by two symmetries and middle respectively have a semicylinder that waits the circular arc steel wire trough (8) of what steel rope semicircle to fix by the screw more than two or two (6) of steel wire trough two sides and form.
